FXYD domain containing ion transport regulator 6 pseudogene 1 (FXYD6P1)

FXYD domain containing ion transport regulator 6 pseudogene 1 (FXYD6P1) is a non-functional genomic DNA segment located on human chromosome 10, derived from duplication or retrotransposition of the functional FXYD6 gene and now considered a pseudogene. Like most pseudogenes, it shares sequence similarity with a protein-coding gene but has lost the ability to code for a functional protein due to disabling mutations such as frameshifts or premature stop codons. Pseudogenes can sometimes exert regulatory effects on cellular RNA/protein levels by acting as decoys for regulatory elements or through transcriptional interference, but no specific such function is documented for FXYD6P1. It is not a receptor, transporter, or any classical druggable target, and is primarily recognized as a genomic relic with no direct known physiological or disease-related function in humans. There is no evidence that FXYD6P1 encodes a functional protein, participates in known biological processes, has established clinical relevance, or serves as a therapeutic target.
