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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-153810179-A-G is Pathogenic according to our data. Variant chr1-153810179-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1029765.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP4: Computational evidence support a benign effect (BayesDel_addAF=-0.0351806).. Strength limited to SUPPORTING due to the PP5.
