The DLX gene family is a group of homeobox genes involved in the development of the craniofacial structures and limbs. They are also implicated in the formation of various organs, such as the brain, inner ear, and teeth. Some possible synonyms for the DLX gene family include Distal-less homeobox, Distal-less-like homeobox, and Drosophila-like homeobox. These names are derived from the fact that the DLX genes share sequence similarities with the Distal-less gene in Drosophila, which is also involved in limb development. Other possible terms that can be used include the DLX cluster, the DLX gene group, or the DLX transcription factor family.
