Genes affected
DMBX1 (HGNC:19026): (diencephalon/mesencephalon homeobox 1) This gene encodes a member of the bicoid sub-family of homeodomain-containing transcription factors. The encoded protein acts as a transcription factor and may play a role in brain and sensory organ development. Two transcript variants encoding distinct isoforms have been identified for this gene.
