Genotyping of nine SHBG-associated single nucleotide polymorphisms (SNP)—rs17496332 PRMT6, rs780093 GCKR, rs10454142 PPP1R21, rs3779195 BAIAP2L1, rs440837 ZBTB10, rs7910927 JMJD1C, rs4149056 SLCO1B1, rs8023580 NR2F2, and rs12150660 SHBG—was executed, and the BC-risk impact of these loci was analyzed by logistic regression separately in each group of obese/non-obese women. Here, PRMT6 is linked to breast cancer.
