title: Correlation between rs198388 and rs198389 polymorphismsin brainnatriuretic peptide (NPPB) gene and susceptibility to congenital heart diseases in a Chinese population.
abstract: OBJECTIVE
  We discussed the correlation between SNP loci (rs198389 and rs198388) in brain natriuretic peptide gene (NPPB) and susceptibility to congenital heart diseases (CHD).
  
  
  METHODS
  Multiplex SNaPshot technique was adopted for profiling of SNP genotypes at loci rs198389 and rs198388 in NPPB gene among 150 cases of CHDand 150 normal controls.
  
  
  RESULTS
  The distribution frequency of 3 genotypes (AA, AG and GG) at locus rs198389 was 40.7%, 36.0% and 23.3% in CHD group, respectively, showing significant differences compared with the normal controls (P<0.001). Gallele was associated with higher risk of CHD (OR=2.48, 95% CI=1.77-3.48). The distribution frequency of CC, CTand TT genotypes at locus rs198388 was 60.7%, 17.3% and 22.0% in CHD group, respectively, also showing significant differences compared with the normal controls (P<0.001). C allele could increase the risk of CHD (OR=1.92, 95% CI=1.48-2.48).
  
  
  CONCLUSIONS
  SNP loci rs198389 and rs198388 in NPPB gene were correlated with genetic susceptibility to CHD.
