| Invitae | RCV001206596 | SCV001377911 | uncertain significance | Tuberous sclerosis 1 | 2022-09-23 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with TSC1-related conditions. 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 TSC1 protein function. ClinVar contains an entry for this variant (Variation ID: 937559). 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 1028 of the TSC1 protein (p.Gly1028Asp). |
| Ambry Genetics | RCV003373029 | SCV004097353 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-04 | criteria provided, single submitter | clinical testing | The p.G1028D variant (also known as c.3083G>A), located in coding exon 21 of the TSC1 gene, results from a G to A substitution at nucleotide position 3083. The glycine at codon 1028 is replaced by aspartic acid, an amino acid with similar 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. |
