Reversion of mtDNA depletion in a patient with TK2 deficiency

Abstract
Mutations in the thymidine kinase 2 (TK2) gene cause a myopathic form of the mitochondrial DNA depletion syndrome (MDS). Here, the authors report the unusual clinical, biochemical, and molecular findings in a 14-year-old patient in whom pathogenic mutations were identified in the TK2 gene. This report extends the phenotypic expression of primary TK2 deficiency and suggests that factors other than TK2 may modify expression of the clinical phenotype in patients with MDS syndrome.
