Variant summary
Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BS1BP5BS3_Supporting
This summary comes from the ClinGen Evidence Repository: The NM_001114753.3: c.1844C>T variant in ENG is a missense variant predicted to cause substitution of serine by leucine at amino acid 615 (p.Ser615Leu). The filtering allele frequency (the lower threshold of the 95% CI of 285/115780) of the c.1844C>T variant in ENG is 0.002284 for European (non-Finnish) chromosomes by gnomAD v2.1.1, which is higher than the ClinGen Hereditary Hemorrhagic Telangiectasia Variant Curation Expert Panel threshold (>0.002) for BS1, and therefore meets this criterion (BS1). This variant has been observed in 1 patient with an alternate molecular basis for disease (patient also carries a likely pathogenic/pathogenic ACVRL1 variant) (BP5; PMID:15712270). The computational predictor REVEL gives a score of 0.188, which is neither above nor below the thresholds predicting a damaging or benign impact on ENG function. However, cellular assays in NIH-3T3 cells showed that BMP9 binding and BMP9 response were all normal, indicating that this variant does not impact protein function (BS3_Supporting; PMID:25312062, 22022569). In summary, this variant meets the criteria to be classified as likely 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: BS1, BP5, BS3_Supporting (specification version 1.0.0; 1/4/2024).

This variant is interpreted as a Likely Benign, for Telangiectasia, hereditary hemorrhagic, type 1, in Autosomal Dominant manner. The following ACMG Tag(s) were applied: BS1 => Allele frequency is greater than expected for disorder (http://exac.broadinstitute.org/variant/9-130578230-G-A). BS2-Supporting => BS2 downgraded in strength to supporting. BP2 => Observed in trans with a pathogenic variant for a fully penetrant dominant gene/disorder or observed in cis with a pathogenic variant in any inheritance pattern (PMID:15712270). -

Haemorrhagic telangiectasia 1 Benign:1
- -
Cardiovascular phenotype Benign:1
This alteration is classified as likely 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. -
