Genetic Testing And Its Social Implications :: essays research papers

Probably, applied hereditarys most impacts on society be as a result of constituenttic tests. In general, genetic tests essay to come upon some feature of a persons genetic constitution. This feature can be a disease causing magnetic declination or a marker DNA sequence used to get wind presence of another gene. Obviously these procedures used for testing the status of DNA, ribonucleic acid or chromosomes be included in genetic tests. What is more it is likely to include some protein based tests and classical medical examinations when they aim to detect inheritance of a trait. Genetic tests have been divided into four categories in this text, and they go away be examined in greater detail later. These categories are prenatal tests that are applied on fetuses during pregnancy. Neonatal screening just after birth and career screening of marrying couples. Testing for serious late-onset disease forward the symptoms occur. Testing to assess the probability of developing compl ex disease. There are a couple of considerations about genetic tests 1. First of all, the tests should be reliable. When a positive or a negative result is obtained, we should be positive(p) in that result with a confidence approaching 100%. To chance upon such a high accuracy is not as unprovoked as it may at first appear to be. Meiotic recombinations that forever and a day occur take place during gamete generation, may separate a disease-associated gene and a marker DNA sequence which is used to detect mutated genes. bastard positive or negative results could be obtained. In addition, genetic tests looking at for the most common mutations that cause the disease. For example, a test would detect CFTR?F508 (Cystic Fibrosis Transmembrane Receptor) mutation, provided it is not possible to detect infinite number of other mutations. Therefore, a genetic test can give such results so that the doc is convinced that his patient is normal while he is affected by an undetectable mutat ion. New tests are continuously being developed. Doctors and genetic counselors who will use these tests in the future, should be well informed about freshly emerging tests. 2. Extremely accurate genetic tests can only be developed by thorough experimentation on human subjects. Although in that respect is generally no physiological risk in experimenting a person, the subjects should be informed that the applied test is not entirely reliable and in experimentation state. Informing subjects of experimentation is an obligation set by the Nuremberg Code. dependable after World War II it was discovered that unethical experiments had been performed on humans who were kept in concentration camps of Nazi Germany.
