Recently, Jin et al. performed a GWAS study and discovered that three novel intronic susceptibility loci in the genes LRFN2 (rs2494938 at 6p21.1), DNAH11 (rs2285947 at 7p15.3) and PLCXD2 (rs2399395 at 3q13.2) were associated with the risk of ESCC in Han Chinese populations [14]. This evidence concerns the gene LRFN2 and esophageal squamous cell carcinoma.
