Genes affected

COX14 (HGNC:28216): (cytochrome c oxidase assembly factor COX14) This gene encodes a small single-pass transmembrane protein that localizes to mitochondria. This protein may play a role in coordinating the early steps of cytochrome c oxidase (COX; also known as complex IV) subunit assembly and, in particular, the synthesis and assembly of the COX I subunit of the holoenzyme. Mutations in this gene have been associated with mitochondrial complex IV deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

Invitae

Jan 18, 2022

This variant is present in population databases (rs752679893, gnomAD 0.0009%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 45 of the COX14 protein (p.Arg45His). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with COX14-related conditions. -
