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.

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jul 18, 2022	This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 4 of the WDR62 protein (p.Val4Leu). This variant is present in population databases (rs147077663, gnomAD 0.03%). 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: 328904). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine 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. -

Jun 03, 2022

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
