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 GeneticsDec 07, 2023The c.466C>G (p.P156A) alteration is located in exon 3 (coding exon 3) of the DMBX1 gene. This alteration results from a C to G substitution at nucleotide position 466, causing the proline (P) at amino acid position 156 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
