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 submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 08, 2021This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 448 of the WDR62 protein (p.Ser448Thr). This variant is present in population databases (rs144072948, gnomAD 0.02%). 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: 286945). 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 threonine 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. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2024The c.1342T>A (p.S448T) alteration is located in exon 10 (coding exon 10) of the WDR62 gene. This alteration results from a T to A substitution at nucleotide position 1342, causing the serine (S) at amino acid position 448 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
