Classes Genetic

Classes Genetic testing is "the analysis of RNA, chromosomes (DNA), proteins, and metabolic processes to detect inherited diseases, interacting with genotype, mutations, phenotypes, or karyotypes for clinical purposes . (Holtzman Watson 1997). It can provide information about a person's genes and chromosomes throughout their lives. The kinds of tests currently available include: Monitoring of newborns: Is used after birth to identify genetic diseases can be treated early. The routine test to check the children is the most common diseases, millions of babies are tested each year in the United States. All states currently screen for the children to check for phenylketonuria (a genetic disease that causes mental retardation if untreated) and congenital hypothyroidism (a disease of the thyroid gland).Additional Exploration: It is used to diagnose or monitor a specific condition of the genes or chromosomes. In many cases, this genetic test is used to confirm a suspected diagnosis when a particular condition based on mutations and physical symptoms. The diagnostic test can be taken at any time during the life of a person, but is not available for all genes or all genetic conditions. The results of a diagnostic test can influence a person's choices about their health and disease control. Review carrier: The carrier test is used to investigate people who carry one copy of a genetic mutation that, when present in two copies, causes a genetic disease. This kind of test is offered to people who have a family history of genetic disorders and people of ethnic groups with an increased risk of specific diseases have genetic.If both parents are examined, the test can provide risk information that has a couple having a child with genetic problems. Prenatal testing: It is used to detect changes in genes or chromosomes of a fetus before birth. This type of test is offered to couples at high risk of having a baby with a genetic disease or chromosomal. In some cases, can reduce the uncertainty of a couple and help them decide whether to abort the pregnancy. Karate Kid Movie However, you can not identify all herary diseases and birth defects. Predictive Test: These tests are used to detect genetic mutations associated with diseases that appear after birth, or even later. These tests can help people who have a family member suffering from a genetic disease, but they themselves do not possess at the time of test. The predictive test can identify mutations that increase a person's chances of developing diseases with a genetic basis, as some types of cancer.For example, a person with BRCA1 mutations have a 65 risk of breast cancer. This test can also predict whether a person can suffer from hemochromatosis before any symptoms appear. The results of these tests can provide information about a person's risk of developing a specific disease and help make decisions about their health care. Genetic fingerprinting: genetic fingerprinting tests using the DNA strands of a person for legal purposes. Unlike the previously described tests, fingerprint evidence is not used to detect mutations associated with disease. Such tests can identify victims of a crime or a disaster, clear or implicate a suspect, or establish biological relationships between people (eg, parenting).Research tests: Tests of research includes the search for unknown genes, learning how genes work and improving understanding of genetic diseases. The results of this test, done as part of a research study not usually available to patients or their physicians.
