Gracia-Aznarez et al. (2013) [16] studied the variant rs144567652 in 3409 BRCA1/2-negative familial BC cases and 3896 controls from Italy, the Netherlands, Australia, and Spain, and the variant was detected in 10 cases (0.3%) and 5 controls (0.1%), with an estimated OR of 2.29 (95% CI = 0.71–8.54, p = 0.13). Here, BRCA1 is linked to breast cancer.
