RCV001217984 | SCV001389848 | uncertain significance | Gastrointestinal stromal tumor; Paragangliomas 4; Pheochromocytoma | 2022-08-31 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SDHB protein function. ClinVar contains an entry for this variant (Variation ID: 947007). This variant has not been reported in the literature in individuals affected with SDHB-related conditions. This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 114 of the SDHB protein (p.Thr114Ser). |
| Ambry Genetics | RCV004034053 | SCV005020176 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-03-14 | criteria provided, single submitter | clinical testing | The p.T114S variant (also known as c.340A>T), located in coding exon 4 of the SDHB gene, results from an A to T substitution at nucleotide position 340. The threonine at codon 114 is replaced by serine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. |
