The prevalence of pathogenic mutations within mitochondrial (mt) DNA of youth who were perinatally exposed to HIV and ART but remained uninfected (YHEU) were assessed relative to phenotypic clinical indicators of mitochondrial dysfunction (MtD). This was a cross-sectional, nested case-control study. A total of 144 cases met at least one clinical MtD definition and were matched with up to two controls each (n = 287). At least one risk mutation was present in nearly all YHEU (97 %). No differences in mutation frequencies were observed between metabolic or neurodevelopmental cases and respective controls; however, higher frequencies were found in controls versus respective neurologic or growth cases.
