Mitochondrial disorders
Gene: COX5A
The rating of this gene has been updated to green and the mode of inheritance updated to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.Created: 2 May 2024, 10:34 a.m. | Last Modified: 2 May 2024, 10:34 a.m.
Panel Version: 6.3
To date, two COX5A variants have been associated with Mitochondrial complex IV deficiency, nuclear type 20 (OMIM:619064) in two unrelated cases (PMID: 28247525;35246835). Analysis of patient fibroblasts has revealed a reduced enzymatic activity and protein levels of complex IV and several of its subunits, plus, lentiviral complementation rescues the complex IV deficiency (PMID: 28247525;35246835).Created: 9 Jan 2024, 12:36 p.m. | Last Modified: 9 Jan 2024, 12:36 p.m.

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Comment when marking as ready: Candidate gene therefore on the red list.Created: 26 Feb 2016, 4:59 p.m.
no mutation reports in literature;
good candidate gene for complex IV deficiency (encodes a subunit of the enzyme)Created: 4 Feb 2016, 1:18 p.m.
Tag Q4_23_promote_green was removed from gene: COX5A.
Source NHS GMS was added to COX5A. Source Expert Review Green was added to COX5A. Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Gene: cox5a has been classified as Amber List (Moderate Evidence).
