Beyond The Genomic Research

Mon, 11 Oct 2010 00:57:35 -0400

The completion of the human genome project was only the beginning in gaining insights on how the instructions contained in the DNA are essential to human life. Researchers are set to obtain more useful knowledge about the DNA sequence. The research studies do not end, therefore. In some countries around the world, genomic research continues. Among other things, the scientists are determined to identify the functions of genes and the factors that coordinate such genes within the genome, discover the 3D structures of proteins and ascertain their roles, and develop and employ DNA-based strategies in order to detect, diagnose and treat disease at an earlier point. Now that the human genome is available, researchers are exploring the patterns by which the proteins and DNA interact with each other and with the environment, thereby, producing complex living systems. The genomic research also seeks to complete the sequencing of other organisms including rat, chimpanzee and cow to have broader and more accurate comparison of genes between these species. Researchers are not too hard to admit that they still have a long way to go before diseases can be understood and treated with perfection. **End Summary** Topics: genomic]]> genomic research]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Genes And Diseases

Mon, 11 Oct 2010 00:55:38 -0400

The influence of genes in diseases is remarkable. There are diseases that are called genetic, including the sickle cell, Duchenne muscular dystrophy, and Down syndrome. These illnesses are caused by genetic variations. On the other hand, diseases such as chicken pox and lung cancer are caused by environmental exposure. Disorders such as certain cancers, dementia, diabetes mellitus, and cardiovascular are triggered both by environmental and genes. Genetic illnesses are classified as single gene or chromosomal disorders, depending on the particular cause of genes. Disorders that are driven by environmental exposure are multi-factoral. This means, that the diseases are a consequence of interaction or additive effects of non-genetic and genetic factors. Although many genetic diseases are rare, they are deemed common as a group, and therefore, they are treated by primary care. Having information about the genetic concepts and more common genetic illnesses are helpful to primary care providers in three ways: First, the information is useful in evaluating the family history, including medical. Second, in differential diagnosis, the genetic disorders are given appropriate consideration. Third, correct use of gene tests and medical genetic services. **End Summary** Topics: genetics]]> genes]]> diseases]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Should You Have A Genetic Testing?

Mon, 11 Oct 2010 00:55:36 -0400

Genetic testing is an investigation of an individual's DNA, including, the RNA, metabolites, and proteins for the purpose of detecting and predicting genetic variations that may have potential for developing illnesses. A gene test is unlike any other tests. Its results are instrumental in shaping decisions as far as treatment and medical management are concerned. It could be clinical in nature so as to examine the specimens and use the results-which are normally done in writing-for diagnosis, prevention or treatment. A gene test can also be a research in nature and the specimens are examined to have a better understanding of a condition, and to develop a specific clinical test. There are laboratories that use genetic testing investigatively, however, the results are not conclusive and generally accepted by other medical scientists. The reasons for obtaining a genetic test vary widely. It could be to detect if an individual is carrying a defective gene or has a disease-carrying genes in his or her DNA makeup. If there is a particular disorder that runs within a family-from first to third generation-members of that family can predict their risks of developing such disorder through a gene test. **End Summary** Topics: genetic testing]]> gene test]]> genetic test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Genetic Research: Prevention And Treatment Of Disease

Mon, 11 Oct 2010 00:53:31 -0400

Even after the Human Genome Project was completed in April 2003, scientists continue to conduct genetic research from different countries. Now that they are one step closer to understanding heredity and diseases, scientists are developing new technologies to prevent certain diseases and to treat them with personalized medicine. For quite some time now, we have been taught by medical experts that common diseases-such as asthma, cancers, diabetes, and heart disease-and rare ones like cystic fibrosis, sickle cell anemia, and hemophilia can run in families. To illustrate, a mother or father who suffers from high blood pressure can pass on such disorder to her or his child when that child becomes an adult. Knowing about one's personal or family medical history can be instrumental in learning whether one is at risk of some diseases, and predicting the risks involved. Once an individual knew that he or she is at risk of developing a genetic disorder, his or her health care provider may devise an individualized plan on a choice of diet, which exercises are recommended, checking regularly for a particular disease, avoidance of excessive alcohol and quitting smoking. **End Summary** Topics: genetic research]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Choosing A Laboratory For Genetic Testing

Fri, 01 Oct 2010 06:04:04 -0400

Genetic testing was supposed to make the search for gene test laboratories simple. However, in some areas, the laboratories are hard to locate. Also, for some diseases, there could only be one laboratory that can provide the appropriate genetic test. There have been US patents issued to cover diagnostic testing for some genetic illnesses. In choosing a laboratory, a few considerations should be taken. This includes the laboratory personnel, compatibility, reliability, ease of communication, location, turnaround time, and cost. The laboratory personnel in-charged with gene tests have two roles-to process the samples of the patients, and to interface with the clinicians about their patients. The laboratory personnel have a license in his field of expertise such as laboratory director, technologists, genetic counselors, and supervisors. To test the compatibility of the laboratory, the gene test provided by the laboratory should match the specific clinical requirements. This involves many things such as having a test methodology that is suitable to the purpose, and ensuring the laboratory that is testing the right genes as some diseases are caused by gene mutations. **End Summary** Topics: genetic testing]]> genetic test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

The Basics Of Human Genetics

Fri, 01 Oct 2010 05:52:02 -0400

The human genome refers to the whole genes of an individual. This includes the DNA, RNA, chromosomes, proteins and metabolites. Within the genome are structures of chromosomes in long double strands, which contain the DNA. Each human being has 23 pairs of chromosomes. Half of each pair is inherited from the person's father, while the other half of the pair is inherited from the person's mother. Of the 23 chromosomes, 22 of them are autosomes, while the remaining pair is composed of the sex chromosomes X and Y. The sex chromosomes determine the sex or gender of an individual. A normal male has and XY chromosome, while a normal female has XX chromosomes. The nucleus is where the chromosomes are located. The DNA of each chromosome is arranged into several subunits-referred to as gene-of genetic information. The genes are composed of nucleotides, which have phosphates, sugar, and nitrogen-containing base. In the DNA are four bases named as adenine, guanine, thymine and cystosine. An individual's uniqueness is determined by the difference in the arrangement of the four bases on each DNA strand. The said arrangement is crucial in producing the RNA, which produces the protein. **End Summary** Topics: genetic variation]]> genetic mutation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Insights On Genetic Testing

Fri, 01 Oct 2010 05:51:28 -0400

Genetic testing provides several advantages both to patients and physicians. The test can be done for diagnosis, prevention and treatment of certain disorders. It can also determine whether an individual has a gene that may bring illness and the chances of the illness to be passed on to the next generation. If the person has been diagnosed of a certain disease, the genetic test can be helpful in determining whether a specific therapy is efficient; if not, it will be helpful in choosing which treatment is best for a patient. The lab personnel involved in gene tests are professionals trained in that field. They are certified to perform the test and interpret the results. During the test, the DNA is extracted and manipulated in many ways so the molecular pathologists or genetic technologists will be able to see the missing or mutating genes that cause a disease. One method of manipulating the DNA is by cutting the genetic material into smaller pieces with the use of special enzymes. The smaller pieces are easier to test than the uncut material, and hence, contain the genes of interest. **End Summary** Topics: genetic test]]> genetic testing]]> gene test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

How Different Is Genetic Testing From Other Tests?

Fri, 01 Oct 2010 05:50:43 -0400

Genetic testing is the process of evaluating and analyzing a person's DNA. This includes the genes, chromosomes, proteins and some metabolites. The purpose of such test is to determine the alterations which can indicate a hereditary illness. The analysis of the genes can be done in many ways depending on the type of test and for what purpose. Though it may share some common characteristics with other laboratory testing, the genetic test is unique in some ways and requires different considerations. Clinical genetic test enables a physician to predict the individual's chances of developing a specific disorder even before the symptoms start to appear, and thus, provides complete diagnosis. It can determine whether a person is a carrier of a defective gene or disease-carrier gene that can be passed on to the next generation. Even the efficiency of a treatment can be ascertained even before it started. Some of the genetic materials that can be used for genetic test include specimens such as urine, blood, stool, saliva, bone, hair and body tissues. The person in-charge will separate the cells in the specimens and extract the DNA for examination of possible alterations and mutations. **End Summary** Topics: genetic testing]]> genetic test]]> gene test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Gene: Variation And Mutation

Fri, 01 Oct 2010 05:50:30 -0400

Polymorphisms or the genetic variations spring from mutation. There are many ways for genetic differences to happen. There is the mitosis, from which the variations occur during the somatic cell division. It could also occur in meiosis or during the process when the cycle of sperm and egg cells has to go through. When these variations occur, lots of consequences can happen. They can be passed along to the offspring, creating more changes over the years, or can result to an illness. At other times, the genetic variations do not bring any apparent effect. Polymorphisms can be classified into different categories, but the most common are silent genetic variations, unstable genetic variation, and stable genetic variation. In silent genetic variations, the mutations or alterations in a gene does not result in changes in the protein product of the gene. Thus, the silent genetic variation can rarely bring an illness. In unstable genetic variations, however, the nucleotide sequence commits several repetitions by itself, hence, it is sometimes called the 'repeat' variation. If the repeat becomes constant and unchanging, this should not pose any threats to the individual. **End Summary** Topics: genetic variation]]> genetic mutation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

The Processes Of Genetic Testing

Thu, 23 Sep 2010 12:16:38 -0400

A Genetic testing is the process of analyzing the DNA and RNA and components such as the chromosomes, proteins and some metabolites for the purpose of detecting any modifications that may be associated with a genetic disorder. The Genetic test can be accomplished in many ways. However, there are selected methodologies in conducting such tests, depending on which approach should apply. These methodologies are grouped into three, DNA-based methodologies, Molecular Cytogenetic methodologies, and Biochemical methodologies. Composing the DNA-based approaches are the Direct DNA testing, Linkage testing, Methylation Studies, Protein Truncation test, Uni-parental Disomy, and X Inactivation studies. Belonging to the Molecular Cytogenetic method is the Fluorescence In Situ Hybridization, while in Biochemical methods are Protein analysis, Enzyme assay, and Analyte. If the professionals performing the Gene test do so by directly examining the DNA or RNA that makes up a gene, the professionals are doing the Direct testing methodology. If the professionals look at the markers that are co-inherited with an illness-carrier gene, they are following the procedure of the Linkage testing. In Biochemical testing, the professionals assay specific metabolites. Cytogenetic testing is done by examining the chromosomes. **End Summary** Topics: genetic testing]]> genetic test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

What To Expect In A Genetic Consultation

Thu, 23 Sep 2010 12:14:15 -0400

A Genetic Consultation is a process of communicating to a concerned individual or family about the occurrence or risk of occurrence of a genetic disease. Such process is driven by five objectives which should be attained by a geneticist, a genetic counselor or any person who received appropriate training, at the conclusion of the Genetic Consultation. First, the genetic professional must be able to acquire and comprehend the medical facts involving the concerned individual-and at some point, his or her immediate and extended family-and including management. Second, the professional must be able to acknowledge and appreciate the contribution of heredity to the disorder, as well as the risk of occurrence in specific family members whether immediate, extended or future. Third, once the risk has been established the geneticist or genetic counselor should be able to understand and recognize the alternatives in deal with such risk. Fourth, help the concerned individual in making them understand the impact of such risks and the availability of courses of action that are in harmony with the individual's unique beliefs, standards, and background in religion, race, ethnic and other concerns. If such independent decision has been made, the geneticist is expected to abide to it. **End Summary** Topics: genetic consultation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Understanding The Process of Ordering A Genetic Testing

Thu, 23 Sep 2010 12:14:02 -0400

A Genetic testing is not performed on an individual unless it is ordered by a Genetic professional. The Genetics professionals may perform first a Genetic counseling or Genetic consultation as most types of Genetic tests require these. As soon as the Genetic professional established the need for a Gene test, it shall be ordered from a laboratory. Genetic professionals are health care professionals who have completed relevant degrees and earned experienced in genetic counseling and medical genetics. They may include genetic counselors, genetic nurses and geneticists. An individual's specialty or primary care provider may also order the Genetic test in his or her behalf. There are four considerations that must be followed in ordering a Gene tests. These are selecting the laboratory, performing a pre-test counseling and getting an informed consent, the availability of sample and its requirements as well as supporting documentation, and the interpretation of test result and follow up appointments. In selecting the laboratory, not much of a choice is available. For some diseases, there may only be one laboratory that provides such tests. In the United States, there were US patents issued to cover Diagnostic test for certain genetic illnesses. **End Summary** Topics: genetic test]]> genetic testing]]> gene test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

What Happens During A Genetic Consultation?

Thu, 23 Sep 2010 12:13:59 -0400

Ever since the Human Genome Project was completed in 2003, medical professionals are better able to determine which genes may be a carrier or a source of a disease which can be genetic in nature. Patients who may be at risk of such diseases are given assistance in understanding the nature of their disease, how and why they acquire them if any, and how they can possibly avoid having such condition. This process of discernment happens in a Genetic Consultation. During such consultation, the individual-whether single or a couple-may seek the professional help of geneticists or genetic counselors through having visits on a doctor's clinic, hospital, genetic center and other medical center. As it is a non-directive course, the person receiving the consultation service will neither expect nor oblige the professional handling the consultation to make the decision, after the result is made available. However, they may support them in reaching their own decisions after unique medical and social circumstances have been analyzed. Because the consultation can be sensitive, the professionals handling the consultation may do their best to help the individuals go through a series of mixed emotions aroused by a diagnosis. **End Summary** Topics: genetic consultation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Understanding A Genetic Consultation

Thu, 23 Sep 2010 12:12:37 -0400

As a healthcare service, a genetic consultation is available for everyone who wishes to gain support and information on whether he or she is at risk of developing genetic disorders. Genetics professionals converged with the individual and family to discuss genetic risks or to rule out, confirm or diagnose a genetic condition. Besides the geneticists, the genetic counselors may be involved in a genetic consultation. Geneticists are medical doctors whose specialization is genetics, while the genetic counselors are certified healthcare professionals who have expertise in counseling and medical genetics. There are also other healthcare professionals such as social workers, psychologists and nurses who can provide consultation on genetics, provided they had a previous training in genetics. Generally, the consultation in genetics, which are in the form of in-person visits with the individual or families, can be done in places such as the hospital, genetics center, doctor's clinic and other types of medical center. It is a very rare case and highly exceptional to have the consultation done over a telephone or in groups. If an individual is considering having a genetic testing, it can be supported with a genetic consultation. **End Summary** Topics: genetic consultation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

The Phases Of Genetic Consultation

Thu, 23 Sep 2010 12:11:50 -0400

Genetic Consultation involves determining whether a certain individual is a carrier of a gene that can cause illness and the risks involved in passing it onto the next generation and recurrence. Before the consultation is accomplished the geneticist or genetic counselor has to completer five phases. These are the Assessment, Evaluation, Communication, Support, and Follow up. During the Assessment, the geneticist or genetic counselor will obtain medical information and family history of the individual seeking the consultation. Then, the information shall be properly interpreted during the Evaluation phase. In the third phase, the genetics professional and or genetic counselor will Communicate the diagnosis to the concerning person and his family to the best of their abilities. The person concerned together with her or his immediate family and other related family members should be made to understand whatever information has been drawn in the first two phases. To make it simple, the genetics professional shall do three things. First, he or she will review the information regarding the illness which shall include the expected course of such illness. Second, the geneticist will describe the risks involved to the family members in comparison to the risks that the general population has. **End Summary** Topics: genetic consultation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Pointers To Remember In Genetic Testing

Thu, 23 Sep 2010 12:11:45 -0400

Genetic testing makes diagnosis, treatment and or prevention of a genetic disease easier and more precise than before its inception. By administering a Genetic test, there will be more room for alternative solutions, more chances of recovery and lesser risks. There are many types of Gene tests conductive depending on the goal of both the individual and the professional ordering the test. Common Genetic tests are Diagnostic, Predictive, Carrier, Pre-natal, Pre-implantation, and Newborn. The definition and pointers for Diagnostic and Predictive testing have already been discussed earlier. Moving forward, the Carrier test is especially helpful to individuals who have a gene mutation for a certain illness inherited in X-linked recessive or autosomal recesive. Most carriers do not manifest the symptoms relevant to the gene mutation. It is particularly recommended to individuals who have family members having a genetic disorder, family members of an identified carrier, and racial and ethnic groups to have a greater rate for a specific condition. To recommend such type of Genetic testing especially to women who plan to have pregnancy, will bound to have other choices for reproduction. As it can have personal and social concerns, the Genetic test should be accompanied with counseling and education. **End Summary** Topics: Genetic testing]]> genetic test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Pointers To Remember In Genetic Testing II

Thu, 23 Sep 2010 12:11:27 -0400

Earlier, the definitions and points to consider in carrying out different types of Genetic Testing were discussed. Genetic test has been helping individuals who are unaware or suspicious that they may be a carrier of genetic condition or at risk of developing such condition. Through a thorough analysis and evaluation of one's DNA, RNA, proteins, chromosomes and some metabolites, genetics professional can determine whether an individual has the gene mutation. There are six different types of Gene test and their function or purpose is indicative of the nature of such test. These tests are Diagnostic, Predictive, Carrier, Pre-natal, Pre-implantation and Newborn. The Genetic tests left for discussion are the Pre-implantation and the Newborn. As the name of the test suggests, the Pre-implantation testing is given on early embryos which are a result of In Vitro Fertilization in pursuit of reducing the chances of having the genetic condition to affect or occur in the fetus. Generally though, the Pre-implantation Genetic testing is recommended to couples who have high chances of passing onto the unborn fetus a serious illness. This type of Gene test is an alternative to Pre-natal test and termination of afflicted conception. **End Summary** Topics: genetic testing]]> genetic test]]> gene test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Five Phases of Genetic Consultation

Thu, 23 Sep 2010 12:10:57 -0400

Genetics Consultation evaluates an individual or a family for four major objectives. First, the process can be done to confirm, diagnose or rule out a genetic condition. Second, it can determine issues on medical management. Third, it is used to appraise and communicate the genetic risks. Fourth, it can be a basis to provide or arrange for psychosocial support. The legitimate parties to perform the Genetic consultation are genetics professionals including the geneticists, genetic counselors, and genetic nurses. These individuals are health care professionals having completed specialized degrees, and acquired solid experience in medical genetics and counseling. These genetic professionals are involved with other members of the health care teams that provide information and support to individuals and family who have genetic illnesses or are at risks of inheriting certain condition. To start with the consultation, the genetic care providers will do visits or phone calls to the concerning individual. The visits can take place individually or by group in a clinic, hospital or genetic centers. Before a consultation is completed, both the professional performing the consultation and the concerning individual will go through four phases, which are the Assessment, Evaluation, Communication, Support, and Follow up. **End Summary** Topics: genetic consultation]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Applications Of Genetic Testing

Thu, 23 Sep 2010 12:08:34 -0400

Genetic Testing seeks to analyze and evaluate the DNA of an individual for the purpose of determining the presence of a gene that is responsible for or has the potential of causing an illness. Should there be any indication of such gene, it is also the responsibility of the medical professional performing the Genet test to appraise the risks involved in developing such disease, risks of passing such disease on to the next generation, and the risks of recurrence. Depending on the type of Gene test given, the application may be used for Diagnostic, Predictive, Carrier, Pre-natal, Pre-implantation, and Newborn. For Diagnostic purposes, the Gene test given is Diagnostic testing. It is the test needed to confirm or rule out any known or suspected gene that can be a cause for a genetic disorder in symptomatic individuals. In carrying out such testing, the professional initiating it should remember some points. The Diagnostic test on the DNA may reap information that should be at a lesser risks and lower cost. It can be administered to anybody who is symptomatic and of any age bracket. In order to successfully establish the diagnosis, the Gene test may require other types of test. **End Summary** Topics: Applications Of Genetic Testing]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Understanding Gene Test

Thu, 09 Sep 2010 00:52:34 -0400

A gene test is a process of investigating a person's DNA to determine alterations that may signal a disorder. To do the test, the person administering it will take cells-in the form of blood or body fluids or tissues-from the patient. The DNA alteration can be large and small. It can be large like an addition to a chromosome, a new chromosome or a missing chromosome, which are all visible with a microscope. It can be small like a modified chemical base, missing chemical base, or having an extra chemical base. Also, the human genes can be overexpressed and have many copies. Or they can be lost or inactivated. There are also circumstances in which the pieces of chromosomes are transported and have the genes in a location where they can be permanently shut off, or the chromosomes are inter-switched. In addition to examining the genes, the chromosomes and the entire DNA, genetic testing also involves biochemical tests to ascertain presence or absence of key proteins that may indicate faulty genes. **End Summary** Topics: gene testing]]> gene test]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

How Do We Inherit Genetic Disorders?

Thu, 09 Sep 2010 00:51:34 -0400

A genetic illness can be caused by mutations in one single cell. There are six different patterns by which genetic disorders can be inherited, depending on which gene is involved. Genetic diseases can be inherited by Autosomal dominant, Autosomal recessive, X-linked dominant, X-linked recessive, Codominant and Mitochondrial. In Autosomal dominant, having one altered copy of the gene suffices for an individual to be afflicted by an Autosomal dominant disease. The person affected by it has one parent who is also affected. Scientists concluded that Autosomal dominant illnesses happen in every generation of an afflicted family. Belonging to this group are diseases such as type 1 neurofibromatosis and Huntington disease. When two copies of a gene are mutated and present in each cell of an individual, then, Autosomal recessive is the pattern by which the genetic disorders follow. In such pattern, the individual affected by it has parents who are not affected but each carries a single copy of the changed gene. Here, the parents are called gene carriers and the Autosomal recessive disorders do not occur in every generation of an afflicted family. Diseases that have Autosomal recessive pattern are cystic fibrosis and sickle cell anemia. **End Summary** Topics: genetic disorder]]> genetic illness]]> genetic disease]]> genetic disorders]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

What You Need To Know About Personalized Medicines

Thu, 09 Sep 2010 00:51:34 -0400

Personalized medicines provide the physicians an effective tool, which is the human genome to treat illnesses based on the patient's DNA or genetic makeup. The application of genomics in pharmacology is called pharmacogenomics. Scientists involved in this research investigate the link between pharmacological properties and the genomic variations. Based on history, statistics are what drives the practice of medicine. To demonstrate, patients would want to be cured as a statistic than an individual because you believe you would likely get well being treated as a statistics. For instance, if you have been diagnosed to have a high blood pressure, and according to a research, 98% of patients with high blood pressure responded well to medication A than to medication B. There is a possibility however that you may belong to a very small group of people who need medication B, while it is less likely that you need medication A. Because there is no effective method to determine whether you belong to a minority or majority group, you would likely take medication A. **End Summary** Topics: personalized medicine]]> DNA]]> ]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

How Does Gene Testing Work?

Thu, 09 Sep 2010 00:50:37 -0400

The Gene testing, the most recent and sophisticated technique used by researchers to determine genetic disease involves the direct investigation of the DNA molecule of the human body. There are also other types of gene testing including the biochemical tests for gene products like the enzymes, and some proteins. There are also microscopic investigations of fluorescent chromosomes or stained chromosomes. Gene tests are generally used for carrier screening, pre-implantation genetic diagnosis, prenatal diagnostic test, newborn screening, verification testing to determine the risk of adult onset cancers and Alzheimer's disease, forensic and identity testing, and pre-symptomatic testing to predict disorders such as Huntington's among adults. In carrier testing, the healthcare provider seeks to identify the unaffected patient who possibly carries one copy of a gene for an illness that needs two copies of genes in order for the illness to be expressed. The pre-implantation genetic diagnostic tests or PGD are commonly done on embryos to screen for diseases. The PGD screens embryos in in vitro fertilization for genetic errors. To accomplish the PGD, the healthcare provider will take DNA samples from the embryos and analyze them for aberrant genes that can cause diseases. **End Summary** Topics: gene testing]]> genetic testing]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

Understanding Genetic Disorders

Thu, 09 Sep 2010 00:50:32 -0400

For a disorder to be termed genetic there should be more than one person in the family affected by it. Many of the illnesses that afflict several members of a family are caused by gene mutations that can be passed on from the parent to the child. However, there are also other disorders that affect many members of the family but are not caused by single gene mutations. Rather, environmental factors like dietary habits or a combination of environmental and genetic components are the culprit. Recognizing a disease to be inherited is not a very easy task. To help genetics professional determine a genetic illness, he will use the family history of an individual. This includes studying the medical records of that individual as well as family members and relatives. The genetics expert will even dig further and inquire on the health condition of family members from first, second and third degrees. The first degree family members are the parents, children, brothers and sisters, while the second degree composes of grandparents, aunts and uncles, grandchildren, nieces and nephews. First cousins belong to the third degree family. **End Summary** Topics: genetic disorders]]> genetic illness]]> genetic disease]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.

The Promises Of Gene Test

Thu, 09 Sep 2010 00:50:25 -0400

Gene test is a process of analyzing an individual's genetic makeup, normally a sample of blood cells, tissues or body fluids for a possible aberrant genes which may carry diseases, which can be passed on to the next generation. It has been available to consumers shortly after the Human Genome Project was completed in 2003. Many physicians recommend genetic testing for a few reasons. First, as a preventative measure, a couple may want to determine whether any of them is a carrier of recessive genetic illnesses which can be passed on to their children, should they plan to have their own family. For a disease to be a recessive, the aberrant gene is inherited in two copies, each from the patient's parents. If only one faulty gene is inherited from one parent, the disease may not be expressed in a child. However, the chance of developing such disease is 50%. The aberrant gene can be identified with a genetic testing. Second, if a person has given birth to a child who has severe birth defect, she may want to find out the cause of such defect. **End Summary** Topics: gene test]]> genetic test]]> gene testing]]> genetic testing]]>]]> About the Author: ]]> Learn how your DNA is the real key to personal wellness: http://www.PowerOfDNA.com One size does not fit all.
