RCV000792200 | SCV000931480 | uncertain significance | Gastrointestinal stromal tumor | 2022-10-16 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 639417). 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 proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 27 of the KIT protein (p.Pro27Leu). |
| Ambry Genetics | RCV004027411 | SCV005033295 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-11-17 | criteria provided, single submitter | clinical testing | The p.P27L variant (also known as c.80C>T), located in coding exon 2 of the KIT gene, results from a C to T substitution at nucleotide position 80. The proline at codon 27 is replaced by leucine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
