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. [provided by RefSeq, Jan 2011]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 6: AlphaMissense, BayesDel_noAF, Cadd, PrimateAI, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.22529003).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000308 (47/152372) while in subpopulation AFR AF = 0.00106 (44/41592). AF 95% confidence interval is 0.000809. There are 0 homozygotes in GnomAd4. There are 19 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
