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]

This variant, c.5827_5841del, results in the deletion of 5 amino acid(s) of the DMXL2 protein (p.Asp1943_Ser1947del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs606231461, gnomAD 0.2%). This variant has been observed in individual(s) with a complex endocrine and neurodevelopmental disorder (PMID: 25248098). ClinVar contains an entry for this variant (Variation ID: 161414). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
