Invitae | RCV002230764 | SCV000543744 | uncertain significance | Juvenile polyposis syndrome | 2016-06-14 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a SMAD4-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 novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. This sequence change replaces arginine with proline at codon 87 of the SMAD4 protein (p.Arg87Pro). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and proline. |
