    ABSTRACT: The aim of present study was to evaluate the association of common polymorphisms detected in mitochondrial DNA (mtDNA) D-loop region (mononucleotide repetitive D310, single nucleotide polymorphism (SNP) D16521) with susceptibility to gastric cancer (GC) in northwestern Chinese population. A total of 180 GC patients and 218 healthy controls were investigated by using PCR- denaturing high performance liquid chromatography (DHPLC) assay. Genotype and allele distributions and haplotype construction were analyzed in case-control study. We found D310 and D16521 heteroplasmy were significantly different between GC cases and controls (p < 0.05), and D16521 homoplasmy showed association with histological grade of GC (p < 0.05). Haplotype 7C/T, 8C/C and 9C/C had significant association with GC risk implied from analysis of D310 and D16521. Taken together, these findings suggested that mtDNA D-Loop polymorphisms and haplotypes may contribute to genetic susceptibility to GC in Chinese population.

    ABSTRACT: non-syndromic cleft lip with or without cleft palate (NSCLP) is one of the most common birth defects all over the world. Both genetic and environmental factors may contribute to NSCLP. Recent studies have demonstrated that Wnt/β-catenin signalling pathway is required for lip and palate formation. WNT family may play an important role in the development of NSCLP. This study aimed to evaluate the association between Wnt3A gene polymorphisms and NSCLP in Chinese population from Northwest China. 216 patients with NSCLP and 233 normal controls were genotyped for two SNPs of Wnt3A by PCR-RFLP. Both SNPs genotype frequencies were analysed between cases group and controls group. the frequencies of rs752107 TT and rs3121310 AA were significantly higher in NSCLP cases group (7.4%, 15.3%) than that in controls group (2.1%, 9.5%) with p-value=0.013, 0.014, corrected p value (p-corr) <0.05 and with odds ratio (OR)=3.49, 95% confidence interval [CI]: 1.244-9.79, OR=2.27, 95% CI: 1.17-4.38, respectively; the frequency of rs3121310 GA was also higher in NSCLP cases group (57.4%) than in controls group (52.0%) with p-value=0.042 and OR=1.56 (95% CI: 1.02-2.39). And the frequency of rs752107 TT of Wnt3A showed higher risk in female patients, while the frequency of A allele of rs3121310 showed stronger association in male patients. this is the first report that two SNPs of Wnt3A (rs752107 and rs3121310) are significantly associated with NSCLP in Chinese population. These findings provide a context for understanding the genetic aetiology of NSCLP.
