Invitae | RCV000800703 | SCV000940433 | uncertain significance | Tuberous sclerosis 2 | 2023-11-22 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 1296 of the TSC2 protein (p.Ser1296Phe). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TSC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 646426). 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 TSC2 protein function with a negative predictive value of 95%. 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 | RCV003166194 | SCV003870259 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-02-24 | criteria provided, single submitter | clinical testing | The p.S1296F variant (also known as c.3887C>T), located in coding exon 32 of the TSC2 gene, results from a C to T substitution at nucleotide position 3887. The serine at codon 1296 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
