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]
WDR62 Gene-Disease associations (from GenCC):
  • microcephaly 2, primary, autosomal recessive, with or without cortical malformations
    Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), Laboratory for Molecular Medicine, Ambry Genetics, Illumina, G2P, ClinGen
  • autosomal recessive primary microcephaly

Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant 19-36100774-C-T is Benign according to our data. Variant chr19-36100774-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 284201.
BP7
Synonymous conserved (PhyloP=-1.91 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000903 (132/1461824) while in subpopulation MID AF = 0.00277 (16/5768). AF 95% confidence interval is 0.00174. There are 0 homozygotes in GnomAdExome4. There are 74 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
