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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.044121265).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000115 (168/1461850) while in subpopulation SAS AF= 0.00154 (133/86258). AF 95% confidence interval is 0.00133. There are 1 homozygotes in gnomad4_exome. There are 117 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 197 of the WDR62 protein (p.Val197Ile). This variant is present in population databases (rs535488873, gnomAD 0.2%). 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: 160306). 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. -
