Genes affected

DVL2 (HGNC:3086): (dishevelled segment polarity protein 2) This gene encodes a member of the dishevelled (dsh) protein family. The vertebrate dsh proteins have approximately 40% amino acid sequence similarity with Drosophila dsh. This gene encodes a 90-kD protein that undergoes posttranslational phosphorylation to form a 95-kD cytoplasmic protein, which may play a role in the signal transduction pathway mediated by multiple Wnt proteins. The mechanisms of dishevelled function in Wnt signaling are likely to be conserved among metazoans. [provided by RefSeq, Jul 2008]

The c.1880G>A (p.R627Q) alteration is located in exon 15 (coding exon 15) of the DVL2 gene. This alteration results from a G to A substitution at nucleotide position 1880, causing the arginine (R) at amino acid position 627 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
