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

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

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: 3.1106 (above the threshold of 3.09). GenCC associations: The gene is linked to hypotonia, ataxia, and delayed development syndrome.

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000197 (3/152218) while in subpopulation SAS AF= 0.000414 (2/4836). AF 95% confidence interval is 0.0000728. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 15 AD gene.
