Invitae RCV001038580 SCV001202057 uncertain significance Juvenile polyposis syndrome 2021-10-06 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. This missense change has been observed in individual(s) with clinical features of SMAD4-related conditions (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 358 of the SMAD4 protein (p.Gly358Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine.
