For CAD patients, HDL-C was positively associated with the transcripts of genes coding cholesterol transporter ATP binding cassette subfamily G member 1 (ABCG1), albumin (ALB), and other proteins involved in cholesterol metabolism (CUBN, HDLBP, and protein kinase cAMP-activated catalytic subunit gamma (PRKACG)). This evidence concerns the gene ABCG1 and coronary artery disorder.
