Genes affected

EBF3 (HGNC:19087): (EBF transcription factor 3) This gene encodes a member of the early B-cell factor (EBF) family of DNA binding transcription factors. EBF proteins are involved in B-cell differentiation, bone development and neurogenesis, and may also function as tumor suppressors. The encoded protein inhibits cell survival through the regulation of genes involved in cell cycle arrest and apoptosis, and aberrant methylation or deletion of this gene may play a role in multiple malignancies including glioblastoma multiforme and gastric carcinoma.

ACMG classification

Verdict is Pathogenic. Variant got 13 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), EBF3. . Gene score misZ: 3.6113 (greater than the threshold 3.09). Trascript score misZ: 3.1409 (greater than threshold 3.09). The gene has 40 curated pathogenic missense variants (we use a threshold of 10). The gene has 6 curated benign missense variants. GenCC has associacion of the gene with hypotonia, ataxia, and delayed development syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.865
• PP5: Variant 10-129957282-G-A is Pathogenic according to our data. Variant chr10-129957282-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 224085.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-129957282-G-A is described in Lovd as [Pathogenic].

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Published functional studies suggest reduced binding and regulatory function, however additional studies are needed to validate the functional effect of this variant in vivo (Harms et al., 2017); This variant is associated with the following publications: (PMID: 28135719, 28017373, 31785789, 28017370, 28554332) -
