Huntington’s disease is a familial disease that is passed down through generations. Out of all cases of HD, 97% of the disease is contracted from parents, and only the small 3% show independent mutation. Moreover, HD is inherited as a dominant trait, meaning a single copy of the mutation is enough to affect offspring. It is therefore vital that couples on high risk of carrying the disease take preventive measures to ascertain the existence of the mutation in their genes for future generations to not pass down the disease further. Methods of genetic screening is largely divided into three – prenatal, predictive and carrier testing. Prenatal testing is done on the fetus in the early stages of pregnancy, whereas predictive and carrier testing is performed on any individual at high risk for having HD. Prenatal testing is usually not recommended for most pregnant mothers, as it carries a high risk of damaging the fetus. Predictive and carrier testing, on the other hand, are harmless methods that determine the existence of the mutation, and thus shows its effectiveness. If couples and individuals…
