HMGA2 antisense RNA 2 (HMGA2-AS2)

There is no credible evidence in the scientific literature or standardized gene nomenclature databases for a *human* gene or transcript named "HMGA2 antisense RNA 2" or abbreviated "HMGA2-AS2". The *HMGA2* gene is a well-characterized chromatin-associated architectural protein involved in developmental regulation and cancer. The main known natural antisense transcript at the HMGA2 locus is **HMGA2-AS1**, which is a long non-coding RNA that regulates HMGA2 gene expression and participates in tumorigenic processes, such as promoting cell migration and proliferation[1]. Most published literature, including regulatory databases and genomic resources (e.g., FANTOM5, HGNC), do not annotate a distinct "HMGA2 antisense RNA 2" entity[1]. It is possible that "HMGA2-AS2" was intended as a reference to HMGA2-AS1 or to another uncharacterized transcript, but as of 2024 this entry is incorrect for structured data purposes. **Summary of issue:** - The canonical antisense for HMGA2 is **HMGA2-AS1**, not HMGA2-AS2. - No evidence exists for HMGA2-AS2 in major databases or published literature[1]. - All structured entries related to "HMGA2 antisense RNA 2" should be set as null or flagged due to incorrect target identification[1]. If you intended to refer to **HMGA2-AS1** (which does have experimental evidence and a defined biological role), please clarify, and information can be provided for that lncRNA. If you are querying for "HMGA2-AS2" specifically, the entry is best classified as a misnomer or placeholder rather than a validated molecular entity.
