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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.886G>A (p.A296T) 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 886, causing the alanine (A) at amino acid position 296 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
