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: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009363294).

BP6

Variant 19-36099544-T-C is Benign according to our data. Variant chr19-36099544-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 195662.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00123 (188/152290) while in subpopulation AFR AF = 0.00435 (181/41568). AF 95% confidence interval is 0.00384. There are 1 homozygotes in GnomAd4. There are 79 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
