Invitae RCV001217016 SCV001388843 uncertain significance Adams-Oliver syndrome 5 2019-07-26 criteria provided, single submitter clinical testing 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. This variant has not been reported in the literature in individuals with NOTCH1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces proline with leucine at codon 226 of the NOTCH1 protein (p.Pro226Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine.
