RCV001853143 | SCV002208022 | uncertain significance | Congenital contractural arachnodactyly | 2021-05-16 | 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, but this prediction has not been confirmed by published transcriptional studies. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FBN2 protein function. This variant has not been reported in the literature in individuals with FBN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 213295). This variant is present in population databases (rs749854367, ExAC 0.001%). This sequence change replaces glycine with arginine at codon 990 of the FBN2 protein (p.Gly990Arg). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and arginine. |
