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]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 424 of the GATAD2B protein (p.Arg424His). This variant is present in population databases (rs375391021, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with GATAD2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 435289). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GATAD2B protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
