Abstract
Although many studies have demonstrated that presenilin-1 plays a vital role in cardiovascular system development, no data are available concerning association of polymorphisms of presenilin-1 with ventricular septal defect (VSD) in the Chinese population. The aim of this study was to evaluate the association between two single-nucleotide polymorphisms (rs1800844 and rs177415) of presenilin-1 and VSD. A total of 151 isolated VSD patients and 296 controls were included in the study. The genotype of the polymorphisms was determined by polymerase chain reaction–restriction fragment length polymorphism. Our study showed no statistically significant differences in genotype and allele frequencies between VSD and controls with any of the presenilin-1 genetic variants. These data may provide evidence that the presenilin-1 gene is not a genetic marker for VSD susceptibility in the Han Chinese population.
