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

ENSG00000291199 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.02).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.884 is higher than 0.05.
