RCV001874751 | SCV002140589 | uncertain significance | Brachyolmia-amelogenesis imperfecta syndrome | 2021-08-05 | criteria provided, single submitter | clinical testing | The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces aspartic acid with glutamic acid at codon 1084 of the LTBP3 protein (p.Asp1084Glu). The aspartic acid residue is weakly conserved and there is a small physicochemical difference between aspartic acid and glutamic acid. This variant has not been reported in the literature in individuals affected with LTBP3-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. |
