However, the involvement in carcinoma (ESCC) development is still largely unclear. We fine-mapped through genotyping 15 haplotype-tagging single nucleotide polymorphisms (htSNPs) using two stage case-control strategy. After analyzing 2098 ESCC patients frequency-matched 2150 unaffected controls, we found that rs2853691, rs2736100 rs451360 genetic are significantly associated with risk Chinese (all P <0.05). Reporter gene assays indicated SNP locating potential TERT intronic promoter genotype-specific effect on expression. Similarly, CLPTM1L also showed allelic impacts measuring expression sixty-six pairs cancer normal tissues, observed G allele carriers elevated oncogene Also, subjects protective T had much lower than those tissue specimens. Results these analyses underline complexity regulation telomere biology further support important role telomerase carcinogenesis. Our data susceptibility.
