Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP5BA1

This summary comes from the ClinGen Evidence Repository: The NM_001114753.3: c.572G>A variant in ENG is a missense variant predicted to cause substitution of glycine by aspartic acid at amino acid 191 (p.Gly191Asp). The filtering allele frequency (the lower threshold of the 95% CI of 1725/109328) of the c.572G>A variant in ENG is 0.01669 for European (non-Finnish) 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). This variant has been observed in at least 2 patients with an alternate molecular basis for disease (patients also carry likely pathogenic/pathogenic ACVRL1 variant) (BP5; PMID:32573726, Internal lab contributors). The computational predictor REVEL gives a score of 0.275, 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, BP5 (specification version 1.0.0; 1/4/2024).

Genes affected
ENG (HGNC:3349): (endoglin) This gene encodes a homodimeric transmembrane protein which is a major glycoprotein of the vascular endothelium. This protein is a component of the transforming growth factor beta receptor complex and it binds to the beta1 and beta3 peptides with high affinity. Mutations in this gene cause hereditary hemorrhagic telangiectasia, also known as Osler-Rendu-Weber syndrome 1, an autosomal dominant multisystemic vascular dysplasia. This gene may also be involved in preeclampsia and several types of cancer. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The NM_001114753.3: c.572G>A variant in ENG is a missense variant predicted to cause substitution of glycine by aspartic acid at amino acid 191 (p.Gly191Asp). The filtering allele frequency (the lower threshold of the 95% CI of 1725/109328) of the c.572G>A variant in ENG is 0.01669 for European (non-Finnish) 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). This variant has been observed in at least 2 patients with an alternate molecular basis for disease (patients also carry likely pathogenic/pathogenic ACVRL1 variant) (BP5; PMID: 32573726, Internal lab contributors). The computational predictor REVEL gives a score of 0.275, 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, BP5 (specification version 1.0.0; 1/4/2024). -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
