Abstract
ObjectiveTo investigate the relationship between NKX2.5 homologous protein (NKX2.5) gene mutation and ventricular septal defect (VSD) in congenital heart disease in Guangxi Zhuang population.
MethodsPolymerase chain reaction (PCR) and DNA detection techniques were used to detect the mutations of all exons and flanking sequences of NKX2.5 gene in 30 patients with VSD and 30 control patients. Nucleic acid polymorphism (SNP) sites were genotyped, and the relationship between the genotype and allele frequencies of a single locus with VSD was analyzed.
ResultsNo mutations were found in NKX2.5 gene in all VSD patients. A SNP locus was found in the second exon region of NKX2.5 gene, located at the 606th position of the upstream base c. 606G>C, belonging to synonymous mutation, in CHD group. There was no significant difference between the VSD group and the control group (genotype frequency comparison: χ2=0.640, P>0.05; allele frequency comparison: χ2=0.034, P>0.05).
ConclusionThere is no significant correlation between NKX2.5 gene mutation and VSD in Guangxi Zhuang population.
