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]

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: -0.059703 (below the threshold of 3.09). Trascript score misZ: 0.15848 (below the threshold of 3.09). GenCC associations: The gene is linked to mitochondrial complex IV deficiency, nuclear type 10, mitochondrial disease, cytochrome-c oxidase deficiency disease.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.868
• PP5: Variant 12-50120100-G-A is Pathogenic according to our data. Variant chr12-50120100-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 31196.Status of the report is no_assertion_criteria_provided, 0 stars.
