Clinical Significance

The Ashkenazi Jewish screening panel currently consists of testing for seven diseases common in the Ashkenazi Jewish population: Bloom syndrome (BLM), Canavan disease (CVN), Familial dysautonomia (FD), Fanconi anemia group C (FA-C), mucolipidosis type IV (MLP4), Niemann Pick disease type A & B (NP) and Tay-Sachs (TSD) disease. Although these conditions have been reported in individuals of various ethnic backgrounds, these diseases occur most frequently in people of Ashkenazi Jewish ancestry. These conditions present when a child receives two copies of an altered gene, one from each parent. Any person with one copy of an altered gene is a carrier of that disease. Carriers are not affected themselves and will not develop the disease. However, if their partner is also a carrier for the same disease, there is a one in four chance (25%) that their baby will be born with the disease condition. There is a three in four chance (75%) that their baby will not have the disease condition.
