ATP binding cassette subfamily D member 1 pseudogene 5 (ABCD1P5)

ATP binding cassette subfamily D member 1 pseudogene 5 (ABCD1P5) is a non-protein-coding locus classified as a pseudogene within the ATP binding cassette transporter family. Pseudogenes, as defined, are genomic sequences similar to functional genes but lack protein-coding capability—either due to mutations or incomplete gene structures[2][6]. ABCD1P5 is located on chromosome 2 (position 91,840,601-91,843,802, forward strand)[3]. There is no evidence for protein expression, interaction with drugs, or direct pathophysiological role. No alternate names or aliases are reported in the referenced gene databases. While some ABC transporter pseudogenes are transcriptionally active and may regulate their parent genes via RNA interference or similar mechanisms[2][4], ABCD1P5 specifically has not been shown to play a functional role, nor is it established as a drug target or biomarker. \n\nThe molecule is best characterized structurally and categorically as a pseudogene, and not as an enzyme, transporter, receptor, or other therapeutically relevant target[9][1][5].\n\nIf you require information on its closely related protein-coding counterpart (e.g., \"ABCD1\"), it is important to distinguish that ABCD1P5 is not the functional gene but a pseudogenic version with no confirmed biological activity[2][9].
