RCV002299692 | SCV002589228 | uncertain significance | Gastrointestinal stromal tumor | 2022-11-03 | criteria provided, single submitter | clinical testing | 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 leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 15 of the KIT protein (p.Leu15Phe). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The phenylalanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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 | RCV004948688 | SCV005608869 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-11-14 | criteria provided, single submitter | clinical testing | The p.L15F variant (also known as c.43C>T), located in coding exon 1 of the KIT gene, results from a C to T substitution at nucleotide position 43. The leucine at codon 15 is replaced by phenylalanine, 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. Based on the available evidence, the clinical significance of this variant remains unclear. |
