The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with a FBN2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with valine at codon 1074 of the FBN2 protein (p.Ile1074Val). The isoleucine residue is moderately conserved and there is a small physicochemical difference between isoleucine and valine. |
