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]
