From this database and a literature review, we selected the CYP19 TTTA repeat and three CYP19 SNPs, rs4646 in the 3′ untranslated region, rs1065779 in the introexon boundary, and rs1870050 in the promoter region/untranslated exon [9–14], which occur at a higher frequency in Han Chinese (see Supplementary Table 1 in the Supplementary Material available online at http://dx.doi.org/10.1155/2013/562197), are associated with cancer risk [9–12], and are suggested to influence aromatase function [13, 14]. This evidence concerns the gene CYP19A1 and cancer.
