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.160A>T (p.T54S) alteration is located in exon 2 (coding exon 2) of the DMBX1 gene. This alteration results from a A to T substitution at nucleotide position 160, causing the threonine (T) at amino acid position 54 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
