Genetic testing for BRCA 1/2 Mutations
Genetic testing for mutations in BRCA 1 or 2 can be performed on a blood sample. In Jewish families the first step is to look for the 3 common Jewish mutations. If this test is normal then it is possible to go onto full BRCA testing if the individual/family wish.
In non-Jewish families it is possible to perform BRCA sequencing, which is where the whole gene code is examined for changes. If possible we prefer to test a living relative who has been affected by breast or ovarian cancer first. When an affected relative is not available or does not wish to be tested it is possible to test an unaffected individual, although this does not give us as much information. Genetic testing usually takes 3 weeks, at which point a follow up appointment is scheduled.
