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 -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.19115907).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000256 (39/152160) while in subpopulation AFR AF= 0.000893 (37/41428). AF 95% confidence interval is 0.000666. There are 0 homozygotes in gnomad4. There are 18 alleles in male gnomad4 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

The c.3589C>A (p.P1197T) alteration is located in exon 30 (coding exon 30) of the WDR62 gene. This alteration results from a C to A substitution at nucleotide position 3589, causing the proline (P) at amino acid position 1197 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The WDR62 c.3589C>A variant is predicted to result in the amino acid substitution p.Pro1197Thr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.060% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-36594319-C-A). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
