A case-control study of the SNPs rs644236 (C > T) and rs7737174 (A > G) within the DROSHA gene demonstrated increased risk of developing breast cancer (OR = 1.27; CI 0.94–1.73, and OR = 1.63; CI 1.01–2.64, for rs644236 and rs7737174, respectively) in Korean post-menopausal women [20]. This evidence concerns the gene DROSHA and breast cancer.
