ABSTRACT

Diabetes was reported to be associated with a mitochondrial (mt) DNA mutation at 3243 and variants at 1310, 1438, 3290, 3316, 3394, 12,026, 15,927, and 16,189. Among these mtDNA abnormalities, those at 3243, 3316, 15,927, and 16,189 were also suggested to cause cardiomyopathies. We investigated the prevalence of such mtDNA abnormalities in 68 diabetic patients with LV hypertrophy (LVH), 100 without LVH, and 100 controls. Among the 9 mtDNA abnormalities, those at 3243, 3316, and 15,927 tended to be more prevalent in diabetic patients with LVH than in those without LVH (1%, 1%, and 4% vs. 0%, 0%, and 0%). Notably, the variant at 16,189 was more prevalent in diabetic patients with LVH than without LVH (46% vs. 24%, [Formula: see text] ). The odds ratio for LVH was 3.0 (95% CI, 1.5-6.1) for the 16,189 variant. A common mtDNA variant at 16,189 was found to be associated with LVH in diabetic patients.
