Invitae RCV000527587 SCV000629537 pathogenic Hereditary hemorrhagic telangiectasia 2019-02-25 criteria provided, single submitter clinical testing This variant is an in-frame deletion of the genomic region encompassing exons 9-10 of the ENG gene. It preserves the integrity of the reading frame. Similar deletions of exons 9-10 have been observed in several individuals affected with hereditary hemorrhagic telangiectasia (PMID: 20414677, Invitae) and observed in an individual with recurrent epistaxis, telangiectasia and multiple pulmonary arteriovenous malformations, findings that are highly specific for this disease (Invitae). Similar deletions are also known as exons 9A-9B deletions in the literature. Variants that disrupt the p.Cys412 amino acid residue in ENG has been observed in affected individuals (PMID: 24196379, 25312062, 15024723, Invitae). This suggests that it is a clinically significant residue, and that other variants that disrupt this residue are likely to be causative of disease. For these reasons, this variant has been classified as Pathogenic.
