Genes affected
GATAD2B (HGNC:30778): (GATA zinc finger domain containing 2B) This gene encodes a zinc finger protein transcriptional repressor. The encoded protein is part of the methyl-CpG-binding protein-1 complex, which represses gene expression by deacetylating methylated nucleosomes. Mutations in this gene are linked to intellectual disability and dysmorphic features associated with cognitive disability. [provided by RefSeq, Jun 2016]
GATAD2B Gene-Disease associations (from GenCC):
  • severe intellectual disability-poor language-strabismus-grimacing face-long fingers syndrome
    Inheritance: AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: ClinGen, G2P, Illumina, Orphanet, Labcorp Genetics (formerly Invitae)
