The most common mutations were 4446C>T and 2953delGTAinsC in BRCA1 and, 6085G>T and 8765delAG in BRCA2. Haplotype analyses of polymorphic microsatellite repeat markers located within and flanking these cancer susceptibility genes have suggested that carriers of the same mutation share a common ancestry [1,6]. Here, BRCA2 is linked to cancer.
