Labcorp Genetics (formerly Invitae), Labcorp RCV001322266 SCV001513129 uncertain significance Gastrointestinal stromal tumor 2020-07-10 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with KIT-related conditions. This sequence change replaces proline with serine at codon 341 of the KIT protein (p.Pro341Ser). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and serine. This variant is not present in population databases (ExAC no frequency). 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 disruptive, 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.
