Labcorp Genetics (formerly Invitae), Labcorp RCV003509839 SCV004244862 pathogenic Telangiectasia, hereditary hemorrhagic, type 2 2023-11-02 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 3 of the ACVRL1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in ACVRL1 are known to be pathogenic (PMID: 15879500). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with hereditary hemorrhagic telangiectasia (Invitae). It has also been observed to segregate with disease in related individuals. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
