Genes affected
DMXL2 (HGNC:2938): (Dmx like 2) This gene encodes a protein with 12 WD domains. Proteins with WD domains are involved in many functions including participation in signal transduction pathways. Participation of the encoded protein in regulation of the Notch signaling pathway has been demonstrated in vitro using several human cell lines (PMID:20810660). A gene encoding a similar protein is located on chromosome 5. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DMXL2. . Gene score misZ 2.3662 (greater than the threshold 3.09). Trascript score misZ 3.2988 (greater than threshold 3.09). GenCC has associacion of gene with polyendocrine-polyneuropathy syndrome, autosomal dominant nonsyndromic hearing loss, nonsyndromic genetic hearing loss, hearing loss, autosomal dominant 71, developmental and epileptic encephalopathy, developmental and epileptic encephalopathy, 81.
BP4
Computational evidence support a benign effect (MetaRNN=0.36114556).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2023The c.9052C>G (p.L3018V) alteration is located in exon 43 (coding exon 43) of the DMXL2 gene. This alteration results from a C to G substitution at nucleotide position 9052, causing the leucine (L) at amino acid position 3018 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
