Mitochondrial Dna Depletion Syndrome 2 (myopathic Type); Mtdps2

Description

Mitochondrial DNA depletion syndrome-2 is an autosomal recessive disorder characterized primarily by childhood onset of muscle weakness associated with depletion of mtDNA in skeletal muscle. There is wide clinical variability; some patients have onset in infancy and show a rapidly progressive course with early death due to respiratory failure, whereas others have later childhood onset of a slowly progressive myopathy (Oskoui et al., 2006).For a discussion of genetic heterogeneity of autosomal recessive mtDNA depletion syndromes, see MTDPS1 (OMIM ).
