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 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-129840963-GACTGCTGGGGAGT-G is Pathogenic according to our data. Variant chr10-129840963-GACTGCTGGGGAGT-G is described in ClinVar as [Pathogenic]. Clinvar id is 421178.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

The c.1402_1414del13 (p.T468Pfs*10) alteration, located in exon 14 (coding exon 14) of the EBF3 gene, consists of a deletion of 13 nucleotides from position 1402 to 1414, causing a translational frameshift with a predicted alternate stop codon after 10 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This variant has been determined to be the result of a de novo mutation in one individual with features consistent with EBF3-related neurodevelopmental disorder (Tanaka, 2017). Based on the available evidence, this alteration is classified as pathogenic. -
