title: Association of a transforming growth factor-β1 polymorphism with acute coronary syndrome in a Chinese Han population.
abstract: Acute coronary syndrome (ACS) is a complex multifactorial and polygenic disorder that is thought to result from the interaction between an individual's genetic makeup and various environmental factors. The aim of this study was to investigate the association of a transforming growth factor-β1 (TGF-β1) polymorphism (-509C>T) with ACS in a Chinese Han population. The TGF-β1 polymorphism was evaluated in 336 patients with ACS and 396 healthy control subjects by polymerase chain reaction-restriction fragment length polymorphism. The genotype distributions of the control and ACS groups were in Hardy-Weinberg equilibrium (X(2) = 3.54 and X(2) = 1.72, respectively, P > 0.05). The frequencies of the CC, CT, and TT genotypes were 22.61, 53.57, and 20.83% in the ACS group, respectively, whereas they were 8.33, 48.74, and 42.17% in controls. There were significant differences between controls and ACS patients in the frequencies of the CC genotype and the C allele. These results suggest that the promoter polymorphism (-509C>T) in TGF-β1 is associated with ACS in this population. The CC genotype and the C allele of TGF-β1 might be a specific risk factor of ACS in the Chinese Han population in Xinjiang.
