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	not provided	Breakthrough Genomics, Breakthrough Genomics	-	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 31, 2023	This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 1123 of the WDR62 protein (p.Gln1123Pro). This variant is present in population databases (rs144233940, gnomAD 0.009%). 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: 586941). 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 WDR62 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. -

The c.3368A>C (p.Q1123P) alteration is located in exon 28 (coding exon 28) of the WDR62 gene. This alteration results from a A to C substitution at nucleotide position 3368, causing the glutamine (Q) at amino acid position 1123 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
