Labcorp Genetics (formerly Invitae), Labcorp RCV001942916 SCV002182980 uncertain significance Brachyolmia-amelogenesis imperfecta syndrome 2023-10-27 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 952 of the LTBP3 protein (p.Asp952Asn). This variant is present in population databases (rs756826691, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with LTBP3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1411235). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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.
