We analyzed the risk candidate allele of HLA-DRB1*01 by genomic real-time polymerase chain reaction together with high-density single nucleotide polymorphisms of the major histocompatibility complex to precisely identify risk loci for acute coronary syndrome with effective clinical implications.
Second, patients with acute coronary syndrome (ACS) (n = 100) and healthy controls (n = 74) were assessed by nine genetic MHC markers (HLA-A, HLA-B, HLA-DRB1, LTA+253(a/g), LTA+496(C/T), LTA+633(c/g), LTA+724(C/A), C4A and C4B), and the frequencies were compared.
