TCF21 and esophageal squamous cell carcinoma: In the SNP analysis we have replicated the newly identified variants (rs12190287 of TCF21, rs10046 of CYP19A1, rs2735940 of TERT, rs751402 of ERCC5, rs2699887 of SLC14A2, rs3792152 of REV1, rs10069690 of TERT, rs2981582 of FGFR2, rs1695 of GSTP1, rs251796 of TERF2, rs2229080 of DCC, rs1801010 of BCL2. Two SNPs that were showing an increased risk of ESCC within the population of our study are rs12190287 of TCF21 and rs10046 of CYP19A1.
