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). Here, SH2B3 is linked to coronary artery disorder.
