About COX20

Cytogenetic location: 1q44 Genomic coordinates (GRCh38): 1:244,835,306-244,845,063 (from NCBI)

This gene has 5 transcripts (splice variants), 181 orthologues and is associated with 2 phenotypes. Ubiquitous expression in thyroid (RPKM 25.6), kidney (RPKM 25.6) and 25 other tissues.

Summary

This gene encodes a protein that plays a role in the assembly of cytochrome C oxidase, an important component of the respiratory pathway. It contains two transmembrane helices and localizes to the mitochondrial membrane. Mutations in this gene can cause mitochondrial complex IV deficiency, which results in ataxia and muscle hypotonia. There are multiple pseudogenes for this gene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]
