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.
There are three types of genetic disorders: 1  Single-gene disorders, where a mutation affects one gene. 2  Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. 3  Complex disorders, where there are mutations in two or more genes.
