From: Mitochondrial DNA m.3243A > G heteroplasmy affects multiple aging phenotypes and risk of mortality
Mitochondrial m.3243A > G association with dementia-related mortality. Survival was compared across tertiles of m.3243A > G heteroplasmy with a total of 263 participants included in each tertile. A significantly increased risk of dementia mortality was observed for participants in the highest tertile of heteroplasmy when compared with those in the lowest tertile (HR = 1.96, 95% CI = 1.11–3.44, p = 0.02). Analyses adjusted for age, sex, race, and clinic site.
