1. Cystic Fibrosis. Cystic Fibrosis is one of the most widespread inherited genetic disorders. It prominently affects Caucasians who are Ashkenazi Jews. It occurs only when both parents are carriers, which gives their children a 1 in 4 risk of contracting the disease.
Genetic traits can be passed through families in several distinct patterns. The most common patterns are the following: 1  Dominant genetic diseases are caused by a mutation in one copy of a gene.2  If a parent has a dominant genetic disease, then each of that personâs children has a 50% chance of inheriting the disease. Dominant diseases can also occur spontaneously; this happens when a random mutation in one gene occurs at conception. 2  Examples of dominant genetic diseases include Achondroplasia and Huntington disease. 3  For some dominant genetic diseases, there may be specific DNA tests available. 4  Recessive genetic diseases.
