Background: The objective of this study was aimed to detect the association of Down syndrome critical region 1 (DSCR1) gene polymorphisms (rs149048873 and rs143081213) and congenital heart disease (CHD) susceptibility. @@@ Material/Methods: This case-control study included 102 CHD patients and 113 healthy controls. Cases and controls were matched in age and gender. Genotypes of DSCR1 gene polymorphisms were detected by TaqMan method in cases and controls. Hardy-Weinberg equilibrium (HWE) examination was performed by PLINK 1.0 software. Chi square test was utilized to assess the distribution of the genotypes and the alleles. Relative risk of CHD was presented by odds ratios (ORs) with 95% confidence intervals (CIs). All of the calculations were implemented using SPSS 18.0. @@@ Results: Variant genotype distribution of rs149048873 and rs143081213 mutations were higher in cases than in controls, but the differences were not statistically obvious (P>0.05). Additionally, frequencies of mutant allele of the two polymorphisms were also significantly different in case and control groups (P>0.05). @@@ Conclusions: No significant associations existed between DSCR1 gene rs149048873 and rs143081213 polymorphisms and CHD susceptibility.
