Genes affected

WDR62 (HGNC:24502): (WD repeat domain 62) This gene is proposed to play a role in cerebral cortical development. Mutations in this gene have been associated with microencephaly, cortical malformations, and cognitive disability. Alternative splicing results in multiple transcript variants.

This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1204 of the WDR62 protein (p.Gly1204Val). This variant is present in population databases (rs587784559, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with WDR62-related conditions. ClinVar contains an entry for this variant (Variation ID: 160293). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
