Invitae | RCV000539964 | SCV000630228 | uncertain significance | Congenital contractural arachnodactyly | 2020-02-07 | criteria provided, single submitter | clinical testing | In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. 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 C45"). This variant is present in population databases (rs747182286, ExAC 0.001%) but has not been reported in the literature in individuals with a FBN2-related disease. This sequence change replaces asparagine with serine at codon 1290 of the FBN2 protein (p.Asn1290Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine. |
