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.
