| Invitae | RCV001046064 | SCV001209949 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2023-12-13 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 313 of the TGFBR2 protein (p.Arg313Leu). This variant is present in population databases (rs200361387, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with TGFBR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 843437). 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 expected to disrupt TGFBR2 protein function with a positive 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. |

RCV001046064 | SCV001358057 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2023-08-24 | criteria provided, single submitter | clinical testing | This missense variant replaces arginine with leucine at codon 313 of the TGFBR2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with TGFBR2-related disorders in the literature. This variant has been identified in 1/251058 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
