RNA, U4 small nuclear 15, pseudogene (RNU4-15P)

RNU4-15P is a pseudogene related to the U4 small nuclear RNA (snRNA) gene and represents a non-functional copy in the human genome[1][3]. The functional U4 snRNA is an essential component of the major spliceosome—the ribonucleoprotein complex responsible for precursor mRNA splicing—but RNU4-15P itself does not encode a functional RNA and is not expressed as part of the spliceosome machinery[1][3][5]. Unlike the two functional U4 snRNA genes (such as RNU4-2), which are associated with neurodevelopmental disorders when mutated[2][5][6], RNU4-15P has not been linked to any biological function or disease role. The term "pseudogene" means it is a genomic sequence resembling a functional gene but typically inactive due to mutations or loss of regulatory elements. Therefore, RNU4-15P is not considered a therapeutic target, biomarker, or specific disease gene. Is the target description incorrect? Yes. RNU4-15P is a pseudogene that does not encode a functional receptor, enzyme, transporter, transcription factor, or channel. If a drug or disease context is intended, the correct target would likely be U4 small nuclear RNA (e.g., RNU4-2), not RNU4-15P. RNU4-15P is described only as a pseudogene and not as a therapeutic target, and thus is not suitable for structured target information[1][3][5]. Summary of family context: The U4 snRNA gene family consists of both functional genes (such as RNU4-2, which is implicated in ReNU syndrome, a neurodevelopmental disorder due to splicing defects[2][5][6]) and pseudogenes like RNU4-15P. Only the functional genes are clinically relevant.
