Ambry Genetics | RCV002446282 | SCV002733962 | uncertain significance | Hereditary cancer-predisposing syndrome | 2020-03-06 | criteria provided, single submitter | clinical testing | The p.E767K variant (also known as c.2299G>A), located in coding exon 16 of the KIT gene, results from a G to A substitution at nucleotide position 2299. The glutamic acid at codon 767 is replaced by lysine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. 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. |

RCV003638889 | SCV004548014 | uncertain significance | Gastrointestinal stromal tumor | 2023-10-09 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 767 of the KIT protein (p.Glu767Lys). 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: 1789212). 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. 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. |
