RCV001894140 | SCV002122244 | uncertain significance | Achondrogenesis, type IB; Atelosteogenesis type II; Multiple epiphyseal dysplasia type 4; Diastrophic dysplasia | 2021-06-07 | 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. 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 SLC26A2 protein function. This variant has not been reported in the literature in individuals with SLC26A2-related conditions. This variant is present in population databases (rs751425859, ExAC 0.009%). This sequence change replaces leucine with valine at codon 682 of the SLC26A2 protein (p.Leu682Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. |
