Association of lipoprotein lipase D9N polymorphism with myocardial infarction in type 2 diabetes The genetics, outcomes, and lipids in type 2 diabetes (GOLD) study

The association of polymorphisms affecting lipid metabolism with the risk of myocardial infarction (MI) in type 2 diabetes mellitus was investigated. The Genetics, Outcomes and Lipids in type 2 Diabetes (GOLD) Study is a prospective, multicenter study, conducted on 990 patients presenting diabetes and MI (n=386), or diabetes without previous manifestation of stroke, peripheral or coronary arterial disease (n=604), recruited from 27 institutions in Brazil. APO A1 (A/G -75 and C/T +83) and APO C3 (C/G 3'UTR) non-coding sequences, CETP (Taq 1B), LPL (D9N), APO E (epsilon2, epsilon3, epsilon4,), PON-1 (Q192R), and two LCAT variants Arg(147)-->Trp and Tyr(171)-->Stop were tested by PCR-RFLP. There was a higher prevalence of LPL DN genotype (19% vs.12%, p=0.03) and a higher frequency of the N allele (11% vs. 7%) among subjects with MI when compared to controls, with an odds ratio of MI for carriers of 9N allele of 2.46 (95% CI=1.79-3.39, p
