Labcorp Genetics (formerly Invitae), Labcorp RCV002851265 SCV003217467 uncertain significance RASopathy 2022-06-27 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with MAP2K2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 6 of the MAP2K2 protein (p.Lys6Arg). 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 MAP2K2 protein function. 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.
