title: Lack of an association between a functional polymorphism in the neuropeptide Y gene promoter and the presence of coronary artery disease in an Iranian population.
abstract: OBJECTIVE
  Several genetic factors have been identified that may contribute to the risk of coronary artery disease (CAD). Variants of the neuropeptide Y (NPY) gene, whose products play an important role in regulating several physiological functions, have been associated with the risk of CAD in some populations. The purpose of this study was to investigate the relationship between the NPY gene rs16147 polymorphism and the presence of CAD in an Iranian population.
  
  
  METHODS
  DNA samples of 922 subjects, including 433 with angiographically defined CAD (CAD+), 196 without angiographically defined significant CAD (CAD-) and 293 controls, were genotyped using polymerase chain reaction based on the amplification-refractory mutation system. Logistic regression analyses were performed to assess the association of rs16147 genotypes with the presence of significant CAD.
  
  
  RESULTS
  Although logistic regression analysis indicated that the NPY polymorphism rs16147 was nominally associated with an increased risk of CAD (p < 0.05), after adjustment for confounding factors, there was no evidence for any signiﬁcantly increased or decreased risk of CAD with this polymorphism. However, in stratiﬁed analyses, the C allele was signiﬁcantly associated with a reduced risk of CAD in males and subjects who were <50 years of age.
  
  
  CONCLUSIONS
  This study suggests that the rs16147 polymorphism in the NPY gene may not be a potential contributor to the risk of CAD in an Iranian population.
