| Invitae | RCV001063027 | SCV001227857 | uncertain significance | Gastrointestinal stromal tumor | 2023-08-16 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 857368). This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 289 of the KIT protein (p.Met289Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with KIT-related conditions. 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 tolerated. 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 | RCV002374960 | SCV002684473 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-23 | criteria provided, single submitter | clinical testing | The p.M289I variant (also known as c.867G>C), located in coding exon 5 of the KIT gene, results from a G to C substitution at nucleotide position 867. The methionine at codon 289 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is conserved. 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. |
