ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001263068 SCV002048569 pathogenic Telangiectasia, hereditary hemorrhagic, type 1 2021-04-06 criteria provided, single submitter clinical testing The ENG c.1411C>T; p.Gln471Ter variant has been described in individuals with hereditary hemorrhagic telangiectasia (Komiyama 2014, Shovlin 2020). The variant is listed in the ClinVar database (Variation ID: 983198) but is absent from general population databases (Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be pathogenic. References: Komiyama M et al. Hereditary hemorrhagic telangiectasia in Japanese patients.

Ambry Genetics RCV002393677 SCV002701775 pathogenic Cardiovascular phenotype 2016-09-29 criteria provided, single submitter clinical testing The p.Q471* pathogenic mutation (also known as c.1411C>T), located in coding exon 11 of the ENG gene, results from a C to T substitution at nucleotide position 1411. This changes the amino acid from a glutamine to a stop codon within coding exon 11. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This alteration was reported in a Japanese family with hereditary hemorrhagic telangiectasia (Komiyama M et al. J. Hum. Genet., 2014 Jan;59:37-41). As such, this alteration is interpreted as a disease-causing mutation.
Invitae RCV002537646 SCV003441485 pathogenic Hereditary hemorrhagic telangiectasia 2022-10-12 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Gln471*) in the ENG gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ENG are known to be pathogenic (PMID: 15879500). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 983198). This premature translational stop signal has been observed in individual(s) with hereditary hemorrhagic telangiectasia (PMID: 24196379). This variant is not present in population databases (gnomAD no frequency).
