To determine whether sex differences affect the association between genetic polymorphisms and coronary artery disease (CAD) in the Chinese Han population, we conducted a study comparing the frequency of SH2B3 and SMARCA4 variants in 456 CAD patients (291 men, 165 women) and 685 age-matched controls (385 men, 300 women). Ten single nucleotide polymorphisms (SNPs) in SH2B3 and SMARCA4 were genotyped using MassARRAY technology. Allelic and genotypic models and haplotype frequencies were compared between groups. Logistic regression was used to estimate the CAD risk associated with the genotypes. We found that the “A” alleles in both rs11879293 and rs12232780 of SMARCA4 were associated with CAD risk in men (p = 0.036 and p = 0.001, respectively). The genetic model showed that SH2B3 was associated with CAD susceptibility in both women and men, while SMARCA4 was associated with reduced odds of CAD in men. SH2B3 haplotypes were associated with decreased CAD risk in women (p = 0.007) and increased CAD risk in men (p = 0.047).By providing evidence for the sex-related association between SH2B3 and SMARCA4 gene variants and CAD susceptibility in the Chinese Han population, this study may help define useful diagnostic and preventive markers for these patients.
