Abstract
Our aim is to verify the association of three Single nucleotide polymorphisms (SNPs) (-218A/G, -254C/G, -361A/T) in the promoter of TRPC6 in 168 sporadic cases with infantile hypertrophic pyloric stenosis (IHPS) and 164 controls in Chinese people.All participants were genotyped using polymerase chain reaction and direct sequencing. And the χ(2) value was calculated. A value of P less than 0.05 was considered statistically significant. We also got the P value of Hardy-Weinberg equilibrium test, and the value of P greater than 0.05 was assumed to be at Hardy-Weinberg equilibrium in this population.The results tell us that there are no significant differences in the allele and genotype frequencies of all these three SNPs between the case and the control groups (P > 0.05).These three TRPC6 SNPs have no association with the IHPS in Chinese people. However, we cannot deny that TRPC6 would be a susceptible gene with IHPS in Chinese people. May be other SNPs in TRPC6 would have some association with the IHPS in Chinese people. But in this study our results may be due to the fact that these SNPs are not the functional SNPs for the development of IHPS in Chinese people.
