Background/aim: Genome-wide association studies revealed a link between gastric cancer (GC) and single nucleotide polymorphisms (SNPs) of prostate stem cell antigen (PSCA), phospholipase C epsilon-1 (PLCE1) and mucin-1 (MUC1) genes. Herein, we aimed to evaluate associations between PSCA (C>T, rs2294008; G>A, rs2976392), MUC1 (C>T, rs4072037) and PLCE1 (A>G, rs2274223) SNPs and GC or high-risk gastritis (HRAG).
Materials and methods: Using TaqMan system, SNPs were genotyped in 252 patients with GC, 136 patients with HRAG and 246 controls.
Results: PSCA rs2294008 allele T was associated with risk of GC (odds ratio (OR)=1.88, p<0.001) and HRAG (OR=1.49, p=0.009). Allele A of PSCA rs2976392 was associated with development of GC (OR=1.88, p<0.001) and HRAG (OR=1.56, p<0.01). MUC1 rs4072037 allele G was protective against development of GC (OR=0.64, p=0.0005), while no differences were found for PLCE1 rs2274223.
Conclusion: Polymorphisms of PSCA (rs2976392, rs2294008) and MUC1 (rs4072037) genes are associated with GC and HRAG.
