VWA5B1 antisense RNA 1 (VWA5B1-AS1)

No verified gene, transcript, or long noncoding RNA named **VWA5B1 antisense RNA 1 (VWA5B1-AS1)** can be found in major genomic, chemical, or molecular target databases as of 2024. There is a protein-coding gene called **von Willebrand factor A domain containing 5B1 (VWA5B1)**[2][8], but there is no documented or characterized antisense RNA with the suffix "-AS1" associated with this locus. By contrast, several well-characterized antisense lncRNAs such as BBOX1-AS1 and OBI1-AS1 exist for other loci, many of which are known to play oncogenic or regulatory roles[1][5]. However, the name "VWA5B1-AS1" does not appear as a recognized entity in scientific literature or databases and may be a misnomer, misspelling, or an uncharacterized/unannotated transcript. **Key context:** - VWA5B1: Encodes a protein (von Willebrand factor A domain containing 5B1); found in human and various mammals[2][8]. - Antisense RNAs (AS1): Many genes have an antisense RNA, typically indicated with the "-AS1" suffix, often lncRNAs with regulatory function[3][7]. However, not all genes have documented antisense transcripts, and uncharacterized or predicted transcripts may not have functional annotation or disease association. - There is robust data on BBOX1-AS1 (for BBOX1), but not for VWA5B1-AS1[1]. **Summary:** "VWA5B1 antisense RNA 1" (VWA5B1-AS1) is not a verified or recognized therapeutic target. There is no evidence for its existence or characterization; thus, all related data (such as molecular class, function, drugs, safety, etc.) must be considered null or missing. This entry appears to be incorrect or incomplete, likely due to a nomenclature or curation error.
