ESR2 and uterine corpus leiomyoma: In the present case control study, a total of five SNPs three in the promoter region given (rs3020449, rs3020450, rs1271572) and two in the exonic region (rs1256049, rs4986938) of the ER-β gene were selected (http://www.ncbi.nlm.nih.gov/snp) and investigated as candidates for conferring variations in all patients with uterine fibroids compared to healthy individuals.
