Invitae RCV001062986 SCV001227814 uncertain significance Hereditary hemorrhagic telangiectasia 2019-10-01 criteria provided, single submitter clinical testing This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 476 of the ENG protein (p.Gln476Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine. This variant has been observed in a family affected with clinical features of hereditary hemorrhagic telangiectasia (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
