Labcorp Genetics (formerly Invitae), Labcorp RCV002037179 SCV002111215 uncertain significance Brachyolmia-amelogenesis imperfecta syndrome 2021-04-14 criteria provided, single submitter clinical testing 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 tolerated, 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. This variant has not been reported in the literature in individuals with LTBP3-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with threonine at codon 778 of the LTBP3 protein (p.Pro778Thr). The proline residue is weakly conserved and there is a small physicochemical difference between proline and threonine.
