RCV000555782 | SCV000630418 | uncertain significance | Gastrointestinal stromal tumor | 2024-01-27 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 470 of the KIT protein (p.Gly470Arg). This variant is present in population databases (rs749914029, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with KIT-related conditions. ClinVar contains an entry for this variant (Variation ID: 458870). 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. 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. |
| Ambry Genetics | RCV002395319 | SCV002698932 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-07-21 | criteria provided, single submitter | clinical testing | The p.G470R variant (also known as c.1408G>A), located in coding exon 9 of the KIT gene, results from a G to A substitution at nucleotide position 1408. The glycine at codon 470 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
