Genes affected

EBF1 (HGNC:3126): (EBF transcription factor 1) Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of transcription, DNA-templated. Predicted to be located in nucleus. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, EBF1
• BP4: Computational evidence support a benign effect (MetaRNN=0.14577094).

Ambry Genetics

Aug 17, 2022

The c.1645G>A (p.V549I) alteration is located in exon 15 (coding exon 15) of the EBF1 gene. This alteration results from a G to A substitution at nucleotide position 1645, causing the valine (V) at amino acid position 549 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
