An extremely rare multiple mitochondrial DNA deletion syndrome with markedly decreased deoxyguanosine kinase (DGUOK) activity in skeletal muscle characterized by a highly variable phenotype. Clinical manifestations include progressive external ophthalmoplegia, mitochondrial myopathy, recurrent rhabdomyolysis, lower motor neuron disease, mild cognitive impairment, sensory axonal neuropathy, optic atrophy, ataxia, hypogonadism and/or parkinsonism.

Also known as: PEOB4, adult-onset multiple mitochondrial DNA deletion syndrome due to DGUOK deficiency, adult-onset multiple mtDNA deletion syndrome due to DGUOK deficiency, progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal recessive 4, progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal recessive type 4, progressive external ophthalmoplegia, autosomal recessive 4
