RNA, U4 small nuclear 21, pseudogene (RNU4-21P)

RNU4-21P is a pseudogene corresponding to the U4 small nuclear RNA gene family. While canonical U4 snRNAs (e.g., RNU4-2) are essential components of the spliceosome required for pre-mRNA splicing and have established roles in neurodevelopmental disorders, RNU4-21P itself is labeled as a pseudogene and is not known to be functionally expressed or implicated in human disease or as a therapeutic target. No evidence supports its role in any biological function, molecular pathway, or clinical application, and it is distinct from the active U4 snRNA genes referenced in recent neurodevelopmental disorder research[1][2][3][5]. Notes: - There is a risk of confusion here as recent research into RNU4-2 (not RNU4-21P) details pathogenic roles of mutations in neurodevelopmental syndromes, but RNU4-21P is a pseudogene with no such evidence[1][2][3][5]. - Being a pseudogene, RNU4-21P is not an active gene nor a protein-coding or regulatory target, and thus is not considered a therapeutic target. - All detailed molecular and clinical functions reported in current literature refer to the active RNU4-2 gene, not RNU4-21P[1][2][3][5].
