Claes et al.  in a 49 BRCA1/2 positive families found six major recurrent founder mutations (three BRCA1 c.212+3A> (BIC: IVS5+3A>G), c.2359dupG (BIC: 2478insG), c.3661G>T (BIC: 3780G>T) and three BRCA2 c.516+1G>A (BIC: IVS6+1G>A), c.6275_6276delTT (BIC: 6503_6504delTT), c.8904delC (BIC: 9132delC) alterations), which accounted for nearly 60% of all mutations identified. BRCA1 c.212+3A>G was previously reported as Belgian founder mutation [92, 93], later also found in a few German, Dutch and French families . BRCA1 c.2359dupG and BRCA2 c.516+1G>A have not yet been reported in other populations.
