RNA, U4 small nuclear 63, pseudogene (RNU4-63P)

RNU4-63P is a non-coding RNA gene annotated as a pseudogene corresponding to the U4 small nuclear RNA family, which normally plays a role as an RNA component of the major spliceosome. However, as a pseudogene, RNU4-63P does not encode a functional small nuclear RNA and is not known to have a biological role or disease association[1][5][7]. RNU4-63P is not a protein, enzyme, receptor, or other canonical drug target; it is listed as a pseudogene—meaning it does not produce a functional product[1][7]. There is no evidence for any biological or clinical function, nor established roles in disease, biomarkers, or known drug interactions for this specific pseudogene[1][7][6]. Pseudogenes like RNU4-63P are typically non-functional copies of genes and rarely serve as therapeutic targets. It is important not to confuse RNU4-63P with functional U4 snRNA genes (such as RNU4-2), which are known to play roles in RNA splicing and may be implicated in neurodevelopmental disorders, but RNU4-63P is not among these functional variants[1][2][3].
