[Genetic polymorphisms in STK15 and MMP-2 associated susceptibility to esophageal cancer in Mongolian population].

Objective: To investigate the frequencies of alleles and the association with risk of esophageal cancer in a Mongolian population, and to compare the allele frequencies of these polymorphisms between the two populations and the susceptibility to esophageal cancer.

Methods: A case-control study was conducted, and 8 single nucleotide polymorphisms (SNP), including FAS - 670G/A, FAS - 1377G/A, FASL -844T/C, COX-2 - 1290A/G, COX-2 - 1195G/A, STK15 Phe31Ile, MMP-2 - 1306C/T and MMP -2 -735C/T, were detected by polymerase chain reaction-based restriction fragment length polymorphism assay (PCR-RFLP) in 188 esophageal cancer cases and 324 normal controls of Mongolian. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by unconditional logistic regression.
