RCV000693878 | SCV000822300 | uncertain significance | Gastrointestinal stromal tumor | 2022-12-13 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 971 of the KIT protein (p.Leu971Pro). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 572486). 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). |
Ambry Genetics | RCV003380684 | SCV004088200 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-16 | criteria provided, single submitter | clinical testing | The p.L971P variant (also known as c.2912T>C), located in coding exon 21 of the KIT gene, results from a T to C substitution at nucleotide position 2912. The leucine at codon 971 is replaced by proline, 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. |
