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 was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.78).
BP6
Variant 19-36092685-G-A is Benign according to our data. Variant chr19-36092685-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 160262.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000775 (118/152320) while in subpopulation AMR AF = 0.0017 (26/15306). AF 95% confidence interval is 0.00119. There are 0 homozygotes in GnomAd4. There are 57 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
