The Wellcome Trust Case Control Consortium (WTCCC) study on 1926 patients and 2938 controls reported strong associations between the chromosome 1p13.3 (rs599839) locus in PSRC1 (NM_032636.7) and CAD (OR for the common risk allele, rs599839 (T), 1.29; 95% CI, 1.18 to 1.40; and adjusted P value = 0.0006).7 Another study performed an association analysis of rs599839 and CAD risk on 11550 patients and 11205 controls from 9 European studies and confirmed this polymorphism association (OR, 1.13; 95% CI, 1.08 to 1.19; and P value = 1.44 × 10−7).8 Here, PSRC1 is linked to coronary artery disorder.
