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.

EBF3 Gene-Disease associations (from GenCC):

• hypotonia, ataxia, and delayed development syndrome

ACMG classification

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

• PM1: In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_001375380.1
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the EBF3 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 40 curated pathogenic missense variants (we use a threshold of 10). The gene has 6 curated benign missense variants. Gene score misZ: 3.6113 (above the threshold of 3.09). Trascript score misZ: 3.1409 (above the threshold of 3.09). GenCC associations: The gene is linked to hypotonia, ataxia, and delayed development syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.873
• PP5: Variant 10-129877811-C-T is Pathogenic according to our data. Variant chr10-129877811-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 545444.Status of the report is criteria_provided_single_submitter, 1 stars.
