Invitae | RCV001322286 | SCV001513149 | uncertain significance | Noonan syndrome 8 | 2020-09-29 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with RIT1-related conditions. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RIT1 protein function. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with leucine at codon 45 of the RIT1 protein (p.Arg45Leu). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and leucine. |
