The Ashkenazi Jewish population has been found to have two common mutations in the BRCA1 gene (185delAG and 5382insC) and one common mutation in BRCA2 gene (6174delT). It is believed that these three mutations account for 26% of the mutations for breast and/or ovarian cancers in the Ashkenazi Jewish population. An incidence of 2-3% for one of these three common mutations has been identified in the general Ashkenazi Jewish population. We will only perform testing within the context of genetic counseling prior to testing to discuss the sensitive issues surrounding presymptomatic testing and again following testing to discuss the implications of results. Please contact laboratory staff for information regarding cancer risk clinics in your area.
