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

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 19-36104568-GTGCC-G is Pathogenic according to our data. Variant chr19-36104568-GTGCC-G is described in ClinVar as [Pathogenic]. Clinvar id is 40.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr19-36104568-GTGCC-G is described in Lovd as [Pathogenic].
