Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 21, 2021 | 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. This variant has not been reported in the literature in individuals affected with KIT-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with arginine at codon 158 of the KIT protein (p.Lys158Arg). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and arginine. 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. - |
