GeneRIFs: Gene References Into Functions

What's a GeneRIF?

This is the first report of primary CoQ10 deficiency caused by loss of function of COQ5, with delineation of the clinical, laboratory, histological, and molecular features, and insights regarding targeted treatment with CoQ10 supplementation.
Title: A novel inborn error of the coenzyme Q10 biosynthesis pathway: cerebellar ataxia and static encephalomyopathy due to COQ5 C-methyltransferase deficiency.
The expression of COQ5 was increased.
Title: Disruption of the human COQ5-containing protein complex is associated with diminished coenzyme Q10 levels under two different conditions of mitochondrial energy deficiency.
The results that knockdown of the COQ5 gene reduced CoQ10 levels further indicated the critical role of COQ5 in the biosynthesis of CoQ10.
Title: Detection of suppressed maturation of the human COQ5 protein in the mitochondria following mitochondrial uncoupling by an antibody recognizing both precursor and mature forms of COQ5.
Observational study of gene-disease association. (HuGE Navigator)
Title: Genetic variants in nuclear-encoded mitochondrial genes influence AIDS progression.

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.
