Invitae RCV001246134 SCV001419474 uncertain significance Achondrogenesis, type IB; Atelosteogenesis type II; Multiple epiphyseal dysplasia type 4; Diastrophic dysplasia 2021-08-24 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 545 of the SLC26A2 protein (p.Arg545His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs745802790, ExAC 0.009%). This variant has not been reported in the literature in individuals affected with SLC26A2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
