DLX2 divergent transcript (DLX2-DT) (DLX2-DT)

DLX2 divergent transcript (DLX2-DT) is a long non-coding RNA (lncRNA) transcribed antisense and head-to-head to the DLX2 gene on human chromosome 2. It is cataloged under aliases including DLX2-AS1 and TCONS_00003049. As a divergent transcript, it emerges from a promoter region shared with the DLX2 coding gene but transcribes in the opposite direction. Divergent lncRNAs are thought to contribute to the regulation of their neighboring gene loci, and may influence chromatin state or form complex regulatory interactions, although the explicit biological function of DLX2-DT remains uncharacterized. There are currently no mechanistic studies or evidence directly linking DLX2-DT to disease phenotypes or therapeutic interventions. Its molecular identity and classification as a non-coding RNA distinguish it from the protein-coding DLX2 gene, which is a well-studied transcription factor critical for craniofacial development. Note: Available studies discussing “DLX2” as a disease and developmental regulator refer to the protein-coding gene, not the divergent lncRNA transcript. Thus, caution should be taken not to conflate these two related but distinct genomic elements.
