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]

Ambry Genetics

Feb 26, 2024

The c.1724C>T (p.T575I) alteration is located in exon 14 (coding exon 14) of the DVL2 gene. This alteration results from a C to T substitution at nucleotide position 1724, causing the threonine (T) at amino acid position 575 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
