Cytochrome c oxidase subunit 5A pseudogene (COX5A pseudogene (no established canonical abbreviation for the pseudogene itself; sometimes referenced as COX5AP1))

Cytochrome c oxidase subunit 5A pseudogene is an inactive, non-protein-coding DNA element in the human genome, showing sequence similarity to the functional COX5A gene. COX5A encodes a nuclear-encoded subunit of Complex IV (cytochrome c oxidase) of the mitochondrial respiratory chain, but this pseudogene cannot produce a functional protein. Pseudogenes are common features of mammalian genomes, generated through gene duplication or retrotransposition, and are typically classified as junk DNA due to lack of coding capacity and regulatory sequences[2][4][5]. They may rarely produce non-coding RNAs with minor or undocumented regulatory functions, but there is no evidence that ENSG00000257296 has any functional or clinical significance. Summary: ENSG00000257296 is not a therapeutic target. It is a pseudogene of COX5A, has no role in disease, function, or pharmacology, and should not be considered for target-based or biomarker studies[2][4][5].
