Evidence submitted by expert panel

Hereditary Hemorrhagic Telangiectasia VCEP

The NM_001114753.3: c.392C>T variant in ENG is a missense variant predicted to cause substitution of proline by leucine at amino acid 131 (p.Pro131Leu). The filtering allele frequency (the lower threshold of the 95% CI of 762/30612) of the c.392C>T variant in ENG is 0.02343 for South Asian chromosomes by gnomAD v2.1.1, which is higher than the ClinGen Hereditary Hemorrhagic Telangiectasia Variant Curation Expert Panel threshold (>0.01) for BA1, and therefore meets this criterion (BA1). The computational predictor REVEL gives a score of 0.315, which is neither above nor below the thresholds predicting a damaging or benign impact on ENG function. In summary, this variant meets the criteria to be classified as benign for autosomal dominant hereditary hemorrhagic telangiectasia based on the ACMG/AMP criteria applied, as specified by the ClinGen Hereditary Hemorrhagic Telangiectasia Variant Curation Expert Panel: BA1 (specification version 1.0.0; 1/4/2024).

Met criteria codes

• BA1: The filtering allele frequency (the lower threshold of the 95% CI of 762/30612) of the c.392C>T variant in ENG is 0.02343 for South Asian chromosomes by gnomAD v2.1.1, which is higher than the ClinGen Hereditary Hemorrhagic Telangiectasia Variant Curation Expert Panel threshold (>0.01) for BA1, and therefore meets this criterion (BA1).

Not Met criteria codes

• PP3: The computational predictor REVEL gives a score of 0.315, which is neither above nor below the thresholds predicting a damaging or benign impact on ENG function.
