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]

Ambry Genetics

Dec 06, 2022

The c.23C>G (p.A8G) alteration is located in exon 2 (coding exon 1) of the COX14 gene. This alteration results from a C to G substitution at nucleotide position 23, causing the alanine (A) at amino acid position 8 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
