ERα gene map, PCR_RFLP and DNA sequencing results: [A] Human ERα map was obtained from NCBI with 22 exons, and PvuII [rs ] SNP is shown in intron 4; [B] Restriction enzyme map: PvuII restriction enzyme of 369-bp PCR fragment in 1% agarose gel [lane M=100-bp DNA marker; lane 1=CC genotype; lane 2=CT genotype; lane 3=TT genotype]; [C] partial sequences of ERα at the rs position.
