Genetics is the study of heredity. The history of genetics began with Gregor Mendel, an Austrian monk in the mid-19th century who provided data to support theoretical ideas posed at the time. Since this time, the molecular basis to genetics has been discovered and, with the completion of the Human Genome Project in 2003, the molecular background of genetics has been deciphered with rapid technological advancements following soon after. This has led to the gaining of knowledge about how genetic factors impact on human disorders. Today, more than 1800 genes have been identified that cause disease and more than 2000 genetic tests have become available to test for them. These technologies, plus the more recently emerging ones, have seen the pace …show more content…
The results of a genetic test can confirm or deny any suspected genetic condition but also to determine a person’s chance of passing or developing a genetic disorder to future generations. Genetic testing has developed more than 1,000 genetic tests and more are still being developed (Genetics Home Reference (unknown), 2017). Genetic testing has been around for almost three decades but has not become compulsory, only voluntary. Testing has benefits but also limitations and risks. The decision about whether to be tested is personal and complex as this decision may involve the partner and if they have different decisions whether to be tested or left unknown. Test results can provide a sense of relief from uncertainty and to also help couples or individuals make decisions to manage their health care. For example, a negative result can eliminate the need for unnecessary check-ups and further tests. Whereas a positive result can direct a person towards prevention, treatment, and monitoring options. Some test results can also help people make decisions about having children either in the future or soon (Genetics Home Reference (unknown), 2017). The tests that will determine the genetic disorder are Amniocentesis and Chronic Villus Sampling and are widely used throughout
