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.

The c.3559G>A (p.V1187M) alteration is located in exon 30 (coding exon 30) of the WDR62 gene. This alteration results from a G to A substitution at nucleotide position 3559, causing the valine (V) at amino acid position 1187 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1187 of the WDR62 protein (p.Val1187Met). 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. 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 methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 160290). This variant has not been reported in the literature in individuals affected with WDR62-related conditions. This variant is present in population databases (rs587784557, gnomAD 0.01%). -
