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
    Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
