Invitae RCV001235941 SCV001408650 uncertain significance Tuberous sclerosis 2 2022-03-13 criteria provided, single submitter clinical testing 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 962136). This variant has not been reported in the literature in individuals affected with TSC2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 1791 of the TSC2 protein (p.Gly1791Asp). 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 RCV002348796 SCV002641638 uncertain significance Hereditary cancer-predisposing syndrome 2022-09-05 criteria provided, single submitter clinical testing The p.G1791D variant (also known as c.5372G>A), located in coding exon 41 of the TSC2 gene, results from a G to A substitution at nucleotide position 5372. The glycine at codon 1791 is replaced by aspartic acid, an amino acid with 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.
