Mitochondrial Dna Depletion Syndrome 4b (mngie Type); Mtdps4b

Description

Mitochondrial DNA depletion syndrome-4B is an autosomal recessive progressive multisystem disorder clinically characterized by chronic gastrointestinal dysmotility and pseudoobstruction, cachexia, progressive external ophthalmoplegia (PEO), axonal sensory ataxic neuropathy, and muscle weakness (van Goethem et al., 2003).For a discussion of genetic heterogeneity of autosomal recessive mtDNA depletion syndromes, see MTDPS1 (OMIM ).
