Chromosomal abnormalities typically occur due to a problem with cell division. Congenital hypertrichosis 8. Most genetic diseases are the direct result of a mutation in one gene. Genetic diseases can also result from changes in DNA in somatic cells, or cells in the body that are not germ cells. Exactly what is sickle cell anemia?

Assisted reproductive therapy techniques can be conducted that test in-vitro embryos for Tay-Sachs before implanting them into the mother. The disease attacks the nerve cells responsible for the control of voluntary muscles. Polycystic kidney disease 10. The following chromosomal problems are the most common: Main symptoms of external manifestations are disproportionately long limbs, slender fingers, and very high growth. Cystic Fibrosis. Tay-Sachs disease. Like Thalassemia, the disease is commonly inherited at a 25 percent rate when both parents have the Cystic Fibrosis gene.
