Among the identified SNPs, 5 BRCA1 SNPs (rs1799950 (4%), rs16942 (64%), rs4986850 (20%), rs2227945 (16%), and rs1799966 (64%)) and 5 BRCA2 SNPs (rs766173 (12%), rs144848 (60%), rs4987117 (4%), rs4987047 (8%), and rs11571833 (4%)) are found to confer minor but cumulatively significant risk of breast cancer (Johnson et al., 2007). Here, BRCA1 is linked to breast carcinoma.
