Invitae | RCV000817962 | SCV000958549 | uncertain significance | Aortic valve disease 2 | 2018-10-11 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine with isoleucine at codon 93 of the SMAD6 protein (p.Met93Ile). The methionine residue is weakly conserved and there is a small physicochemical difference between methionine and isoleucine. 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 variant has not been reported in the literature in individuals with SMAD6-related disease. 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. |
