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.
These are genetic diseases that are due to an abnormal number or structure of the chromosomes. A frequent chromosome anomaly is Down syndrome. These are genetic diseases that are due to a mutation(s) in only 1 gen. They can be inherited in different ways: autosomal dominant, autosomal recessive, X-linked or Y-linked. Frequent monogenic diseases are cystic fibrosis, thalassemia and fragile X syndrome.
