Invitae | RCV000700226 | SCV000828974 | uncertain significance | Gastrointestinal stromal tumor; Paragangliomas 3 | 2023-10-27 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 5 of the SDHC protein (p.Leu5Ser). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 577464). 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 | RCV002388305 | SCV002702087 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-10-12 | criteria provided, single submitter | clinical testing | The p.L5S variant (also known as c.14T>C), located in coding exon 1 of the SDHC gene, results from a T to C substitution at nucleotide position 14. The leucine at codon 5 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is well 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. |
