C4A antisense RNA 1 (C4A-AS1)

C4A antisense RNA 1 (C4A-AS1) is an annotated antisense long non-coding RNA (lncRNA) mapped to the human C4A gene locus (complement component 4A), with record in the NCBI Gene database (Gene ID: 106478955)[5]. As with other antisense RNAs, it is transcribed from the strand opposite to its associated coding gene (C4A), but to date, there are no functional studies or reports describing its role, biological activity, disease associations, or relevance as a therapeutic target. It does not appear in the scientific literature as a characterized or actionable molecule. Therefore, its significance and function remain unknown. If you intended a different or more established antisense RNA (for example, those associated with diseases or studied in functional biology or oncology), please clarify or provide an alternate name, as "C4A antisense RNA 1" currently lacks sufficient scientific characterization[5].
