RCV001360634 | SCV001556561 | uncertain significance | Gastrointestinal stromal tumor | 2021-10-02 | 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with KIT-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with arginine at codon 953 of the KIT protein (p.His953Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. |

Ambry Genetics | RCV004951604 | SCV005608778 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-11-15 | criteria provided, single submitter | clinical testing | The p.H953R variant (also known as c.2858A>G), located in coding exon 21 of the KIT gene, results from an A to G substitution at nucleotide position 2858. The histidine at codon 953 is replaced by arginine, 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. |
