Invitae | RCV000550456 | SCV000630223 | uncertain significance | Congenital contractural arachnodactyly | 2017-03-27 | criteria provided, single submitter | clinical testing | This sequence change replaces serine with tyrosine at codon 1205 of the FBN2 protein (p.Ser1205Tyr). The serine residue is highly conserved and there is a large physicochemical difference between serine and tyrosine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a FBN2-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. |
