RCV000822470 | SCV000963273 | uncertain significance | Gastrointestinal stromal tumor | 2024-01-04 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 184 of the KIT protein (p.Leu184Met). 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. ClinVar contains an entry for this variant (Variation ID: 664382). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The methionine 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 | RCV002345903 | SCV002653542 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-11-22 | criteria provided, single submitter | clinical testing | The p.L184M variant (also known as c.550C>A), located in coding exon 3 of the KIT gene, results from a C to A substitution at nucleotide position 550. The leucine at codon 184 is replaced by methionine, 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. |
