Human Genetic Screening Essay -- Genes Science Papers

homo familial ScreeningWhat is transmissible back? Genetic screening is the interrogation of cells to check for certain kinds of genes, or for potentially damaging changes to those genes. It may be defined as a systematic search for persons with a specific genotype in a defined population. Genetic screening serves as an important adjunct of modern preventive medicine. The usual approach is to station persons whose genotype places them or their offspring at risk for genetic illnesss. much(prenominal) screening has the potential to lessen the devastating impact of genetic diseases. Genetic screening may be undertaken for research purposes unrelated to disease or the improvement of health. The National Academy of Sciences recommends that genetic screening is an appropriate systema skeletale of medical c atomic number 18 only when certain conditions are met. These include (1) turn out of substantial world benefit and acceptance, (2) the benefits outweigh the costs (3) appropri ate public education can be carried out (4) informed consent is possible (5) the means are available to evaluate the effectiveness and success of severally step in the process (Blank, 1982). Some screening is aimed at the popular population, while others are targeted at selective high-risk population screening can also be conducted at various stages of life. There are three principal types of genetic screening. (1) Newborn screening identifies serious genetic disease at birth, permitting prompt treatment to prevent mental and visible retardation. (2) Fetal screening and prenatal diagnosis identify genetic disease in the fetus permitting selective termination of pregnancy and the opportunity to stool children free of defects detectable in uterus. (3) Carrier screening identifies individuals hete... ...5. Fost, N., 1993. Genetic diagnosis and treatment, American Journal of Diseases of Children. 147(11)1190-1195. 6. Knoppers, B.M., 1986.
