Labcorp Genetics (formerly Invitae), Labcorp RCV001343906 SCV001537925 uncertain significance Achondrogenesis, type IB; Atelosteogenesis type II; Multiple epiphyseal dysplasia type 4; Diastrophic dysplasia 2020-03-10 criteria provided, single submitter clinical testing This sequence change replaces proline with threonine at codon 606 of the SLC26A2 protein (p.Pro606Thr). The proline residue is highly conserved and there is a small physicochemical difference between proline and threonine. This variant is present in population databases (rs767618201, ExAC 0.001%). This variant has been observed in an individual with diastrophic dysplasia (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. 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 and their clinical significance is uncertain. 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.
