Rho GTPase activating protein 27 pseudogene 2 (ARHGAP27P2)

Rho GTPase activating protein 27 pseudogene 2 (ARHGAP27P2) is classified as a pseudogene, meaning it is a nonfunctional DNA segment that resembles the functional ARHGAP27 gene but does not encode an active protein product in humans[3][7][8][9][10]. Pseudogenes like ARHGAP27P2 arise through gene duplication or retrotransposition events and typically contain significant mutations or disruptions (such as frameshifts or premature stop codons) that prevent production of a functional protein[10]. As such, ARHGAP27P2 is not a therapeutic or biological target (such as a receptor or enzyme) and does not possess described molecular function, associated disease roles, or drug interactions. It serves primarily as a genomic relic with no known physiological or pathological function in humans[9][10].\n\nKey clarification:\nAlthough the closely related ARHGAP27 gene encodes an active member of the Rho GTPase activating protein family involved in cytoskeletal regulation and is implicated in several diseases, ARHGAP27P2 is a distinct, nonfunctional pseudogene and does not have the same functional or therapeutic relevance[1][3][5][9].
