Novel transcript, antisense to SH2D3C (ENSG00000299648)

This molecule is a long non-coding RNA (lncRNA) identified as antisense to the SH2D3C gene locus. It is cataloged in genetic databases as ENSG00000299648 and does not produce a protein product[1]. There is no evidence that it serves as a therapeutic target, and no specific biological functions, disease roles, or drug interactions have been described in the literature for this transcript. Its presence as an antisense lncRNA might suggest some potential for *cis*-regulatory roles affecting SH2D3C expression, but this function is not established. This transcript is distinct from the protein-coding SH2D3C gene, which is an adaptor protein involved in cell signaling[5]; this lncRNA should not be confused with the protein target.
