Ambry Genetics | RCV002340037 | SCV002638501 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-08-02 | criteria provided, single submitter | clinical testing | The p.S151C variant (also known as c.452C>G), located in coding exon 6 of the SDHC gene, results from a C to G substitution at nucleotide position 452. The serine at codon 151 is replaced by cysteine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV003102596 | SCV003198083 | uncertain significance | Gastrointestinal stromal tumor; Paragangliomas 3 | 2021-11-25 | 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with SDHC-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 151 of the SDHC protein (p.Ser151Cys). |
