Genes affected

DVL1 (HGNC:3084): (dishevelled segment polarity protein 1) DVL1, the human homolog of the Drosophila dishevelled gene (dsh) encodes a cytoplasmic phosphoprotein that regulates cell proliferation, acting as a transducer molecule for developmental processes, including segmentation and neuroblast specification. DVL1 is a candidate gene for neuroblastomatous transformation. The Schwartz-Jampel syndrome and Charcot-Marie-Tooth disease type 2A have been mapped to the same region as DVL1. The phenotypes of these diseases may be consistent with defects which might be expected from aberrant expression of a DVL gene during development. [provided by RefSeq, Jul 2008]

The c.1955G>A (p.R652H) alteration is located in exon 15 (coding exon 15) of the DVL1 gene. This alteration results from a G to A substitution at nucleotide position 1955, causing the arginine (R) at amino acid position 652 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DVL1 protein function. ClinVar contains an entry for this variant (Variation ID: 1054652). This variant has not been reported in the literature in individuals affected with DVL1-related conditions. This variant is present in population databases (rs376204834, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 652 of the DVL1 protein (p.Arg652His). -
