Invitae | RCV000456752 | SCV000548946 | uncertain significance | Adams-Oliver syndrome 5 | 2019-10-02 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with serine at codon 251 of the NOTCH1 protein (p.Gly251Ser). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and serine. This variant is present in population databases (rs755667439, ExAC 0.009%) but has not been reported in the literature in individuals with a NOTCH1-related disease. 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. In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |
