Association of E-cadherin (CDH1) gene polymorphisms and gastric cancer risk

AIM:To investigate the associations between CDH1 gene polymorphisms and gastric cancer(GC) risk predisposition.METHODS:We analyzed four CDH1 polymorphisms(+54 T>C,-160 C>A,-616 G>C,-3159 T>C) in an Omani population,by extraction of genomic DNA from the peripheral blood of 192 patients with GC and 170 control participants and performed CDH1 genotyping using DNA sequencing.RESULTS:CDH1-160-AA genotype was associated with an increased risk of GC(OR = 3.6,95% CI:1.1-11.8)(P = 0.03).There was no significant asso...
