Invitae RCV001043873 SCV001207640 uncertain significance Adams-Oliver syndrome 5 2019-05-13 criteria provided, single submitter clinical testing This sequence change replaces cysteine with arginine at codon 321 of the NOTCH1 protein (p.Cys321Arg). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with NOTCH1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
