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

Classification was made for transcript

Our verdict: Benign. The variant received -18 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr1-153818093-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 2626873.

BP4

Computational evidence support a benign effect (MetaRNN=0.0072884858).

BP6

Variant 1-153818093-G-C is Benign according to our data. Variant chr1-153818093-G-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 129136.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00532 (810/152304) while in subpopulation AFR AF = 0.0186 (775/41568). AF 95% confidence interval is 0.0176. There are 6 homozygotes in GnomAd4. There are 376 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 810 AD gene.
