RCV001189514 | SCV001356823 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2023-12-05 | criteria provided, single submitter | clinical testing | Variant of Uncertain Significance due to insufficient evidence: This missense variant is located in the triple-helical region of the COL3A1 protein. Computational prediction tools and conservation analyses suggest that this variant may have deleterious impact on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 4/246176 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the pathogenicity of this variant conclusively. |

RCV001852259 | SCV002148466 | uncertain significance | Ehlers-Danlos syndrome, type 4 | 2021-05-13 | criteria provided, single submitter | clinical testing | 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. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with COL3A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 199738). This variant is present in population databases (rs780788248, ExAC 0.009%). This sequence change replaces arginine with histidine at codon 1034 of the COL3A1 protein (p.Arg1034His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. |
