Entrez Gene Summary for C12orf65 Gene

  • This nuclear gene encodes a mitochondrial matrix protein that appears to contribute to peptide chain termination in the mitochondrial translation machinery. Two different 1 bp deletions (resulting in the same premature stop codon)result in decreased mitochondrial translation, decreased levels of oxidative phosphorylation complexes and encepthalomyopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]

GeneCards Summary for C12orf65 Gene

C12orf65 (Chromosome 12 Open Reading Frame 65) is a Protein Coding gene. Diseases associated with C12orf65 include spastic paraplegia 55, autosomal recessive and combined oxidative phosphorylation deficiency 7. GO annotations related to this gene include translation release factor activity.

  • Combined oxidative phosphorylation deficiency 7 (COXPD7) [MIM:613559]: A mitochondrial disease resulting in encephalomyopathy. Clinical manifestations include psychomotor delay and regression, ataxia, optic atrophy, nystagmus and muscle atrophy and weakness. {ECO:0000269 PubMed:20598281}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Spastic paraplegia 55, autosomal recessive (SPG55) [MIM:615035]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. Complicated forms are recognized by additional variable features including spastic quadriparesis, seizures, dementia, amyotrophy, extrapyramidal disturbance, cerebral or cerebellar atrophy, optic atrophy, and peripheral neuropathy, as well as by extra neurological manifestations. {ECO:0000269 PubMed:23188110}. Note=The disease is caused by mutations affecting the gene represented in this entry.
