Labcorp Genetics (formerly Invitae), Labcorp RCV000693967 SCV000822391 uncertain significance Gastrointestinal stromal tumor 2023-08-04 criteria provided, single submitter clinical testing 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 572558). This variant has not been reported in the literature in individuals affected with KIT-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 135 of the KIT protein (p.Arg135Cys).
