RCV001921753 | SCV002198948 | uncertain significance | Aortic valve disease 2 | 2021-09-14 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with SMAD6-related conditions. 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 proline with leucine at codon 90 of the SMAD6 protein (p.Pro90Leu). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and leucine. |
