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]

Nov 06, 2023

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 41 of the COX14 protein (p.Arg41His). This variant is present in population databases (rs141173025, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with COX14-related conditions. ClinVar contains an entry for this variant (Variation ID: 1939917). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
