Similar associations were observed for two other highly correlated variants (r2 >0.8) on chromosome 11, namely rs183459 (p = 5.7 × 10−3) also located within NPAT and rs228592 (p = 5.5 × 10−3) located in intron 11 of ATM. No association was observed between SNPs at this locus and breast cancer risk for BRCA2 carriers (Online Resource 5). Here, BRCA2 is linked to breast cancer.
