Recent advances in molecular diagnostics have improved our understanding of these complex disorders. However, the extensive genetic and phenotypic heterogeneity of MCs remains only partially characterized and the correlations between specific genetic variants and clinical manifestations are just beginning to be unraveled. We hereby describe the phenotypic and genotypic variability of a cohort of 49 patients with MC.engMitochondrial CytopathiesRespiratory ChainInborn Metabolic DisordersDoenças GenéticasAdvances in the diagnosis and understanding of mitochondrial cytopathies: a retrospective study of genetic and clinical variabilityconference object
