RCV003057735 | SCV003348350 | uncertain significance | Costello syndrome | 2022-04-21 | criteria provided, single submitter | clinical testing | 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 expected to disrupt HRAS protein function. This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 159 of the HRAS protein (p.Leu159Phe). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with HRAS-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. |
