RCV001213680 | SCV001385325 | uncertain significance | Gastrointestinal stromal tumor; Paragangliomas 3 | 2023-12-05 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 92 of the SDHC protein (p.Leu92Phe). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SDHC-related conditions. ClinVar contains an entry for this variant (Variation ID: 943485). 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 tolerated. 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 | RCV004033902 | SCV005020188 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-11-09 | criteria provided, single submitter | clinical testing | The p.L92F variant (also known as c.274C>T), located in coding exon 5 of the SDHC gene, results from a C to T substitution at nucleotide position 274. The leucine at codon 92 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is conserved. 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. |
