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.

The c.866G>A (p.G289E) alteration is located in exon 4 (coding exon 4) of the DMBX1 gene. This alteration results from a G to A substitution at nucleotide position 866, causing the glycine (G) at amino acid position 289 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
