A high-molecular-weight protein complex containing COQ5, but not COQ9, in the mitochondria was identified and its level was suppressed by FCCP and in cybrids with MERRF mutation.
Bilateral putaminal necrosis associated with the mitochondrial DNA A8344G myoclonus epilepsy with ragged red fibers (MERRF) mutation: an infantile case.
Cerebellar ataxia is common in myoclonic epilepsy with ragged red fibers (MERFF) due to mutations in the mitochondrial transfer RNA (tRNA) lysine gene, in Kearns-Sayre syndrome due to mtDNA deletions, in sensory ataxic neuropathy with dysarthria and ophthalmoplegia (SANDO) due to nuclear POLG1 gene mutations, and also in ARCA2, Friedreich's ataxia, SPG7, SCA28 and autosomal-recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) due to mutations in nuclear genes involved in mitochondrial morphology or function.
