The low-density lipoprotein receptor class A domain containing 1 gene (LDLRAD1) on chromosome 1 contained seven rare variants (S3 Table) and was significantly associated with prevalent CHD (P = 1.30 × 10−6, OR = 4.48, 95% confidence interval: 2.44, 8.23; Table 2). The gene discussed is LDLRAD1; the disease is coronary artery disorder.
