Summaries for COX14 Gene

Entrez Gene Summary for COX14 Gene

  • 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]

GeneCards Summary for COX14 Gene

COX14 (COX14 Cytochrome C Oxidase Assembly Factor) is a Protein Coding gene. Diseases associated with COX14 include Mitochondrial Complex Iv Deficiency and Isolated Cytochrome C Oxidase Deficiency. Among its related pathways are Gene Expression and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins..

  • Note=Defects in COX14 may be a cause of a mitochondrial disorder presenting with severe congenital lactic acidosis and dysmorphic features associated with a COX assembly defect. Other features include brain hypertrophy, diffuse alteration of the white-matter myelination, and numerous cavities in the parieto-occipital region, brainstem, and cerebellum, as well as hepatomegaly, hypertrophic cardiomyopathy, renal hypoplasia, and adrenal-gland hyperplasia. {ECO:0000269 PubMed:22243966}.
