| Invitae | RCV001052219 | SCV001216419 | uncertain significance | Gastrointestinal stromal tumor | 2023-08-01 | 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: 848455). This variant has not been reported in the literature in individuals affected with KIT-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 903 of the KIT protein (p.Met903Thr). |
| Ambry Genetics | RCV002436606 | SCV002744981 | uncertain significance | Hereditary cancer-predisposing syndrome | 2020-03-30 | criteria provided, single submitter | clinical testing | The p.M903T variant (also known as c.2708T>C), located in coding exon 20 of the KIT gene, results from a T to C substitution at nucleotide position 2708. The methionine at codon 903 is replaced by threonine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
