Mitochondrial Dna Depletion Syndrome 3, also known as deoxyguanosine kinase deficiency, is related to mitochondrial dna depletion syndrome 6 and progressive external ophthalmoplegia with mitochondrial dna deletions, autosomal recessive 4, and has symptoms including icterus, seizures and vomiting. An important gene associated with Mitochondrial Dna Depletion Syndrome 3 is DGUOK (Deoxyguanosine Kinase), and among its related pathways/superpathways is Peroxisomal lipid metabolism. Affiliated tissues include liver and eye, and related phenotypes are failure to thrive and hepatic failure
