Dystonia and Parkinsonism in COA7-related disorders: expanding the phenotypic spectrum.
Title: Dystonia and Parkinsonism in COA7-related disorders: expanding the phenotypic spectrum.
Mitochondrial COA7 is a heme-binding protein with disulfide reductase activity, which acts in the early stages of complex IV assembly.
Title: Mitochondrial COA7 is a heme-binding protein with disulfide reductase activity, which acts in the early stages of complex IV assembly.
pathogenic mutant versions of COA7 are imported slower than the wild-type protein, and mislocalized proteins are degraded in the cytosol by the proteasome.
Title: Inhibition of proteasome rescues a pathogenic variant of respiratory chain assembly factor COA7.
The results of this study suggest that loss-of-function COA7 mutation is responsible for the phenotype of the presented patients, and this new entity of disease would be referred to as spinocerebellar ataxia with axonal neuropathy type 3.
Title: Mutations in COA7 cause spinocerebellar ataxia with axonal neuropathy.
The first patient carrying pathogenic mutations of COA7, causative of isolated COX deficiency and progressive neurological impairment is reported. It is also shown that COA7 is a soluble protein localized to the matrix, rather than in the intermembrane space as previously suggested.
Title: COA7 (C1orf163/RESA1) mutations associated with mitochondrial leukoencephalopathy and cytochrome c oxidase deficiency.
C1orf163 is a novel factor important for the assembly of respiratory chain complexes in human mitochondria.
Title: C1orf163/RESA1 is a novel mitochondrial intermembrane space protein connected to respiratory chain assembly.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
