RCV001227423 | SCV001399782 | uncertain significance | Ehlers-Danlos syndrome, type 4 | 2022-06-03 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 COL3A1 protein function. ClinVar contains an entry for this variant (Variation ID: 954889). This variant has not been reported in the literature in individuals affected with COL3A1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 65 of the COL3A1 protein (p.Ile65Val). |

RCV001806062 | SCV002053032 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2021-04-29 | criteria provided, single submitter | clinical testing | This missense variant replaces isoleucine with valine at codon 65 of the COL3A1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 1/250790 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. |
