Color Diagnostics, LLC DBA Color Health RCV001190568 SCV001358078 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2023-12-05 criteria provided, single submitter clinical testing This missense variant replaces serine with arginine at codon 1425 of the COL3A1 protein. Computational prediction tools and conservation analyses suggest that this variant may not impact 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 not been identified in the general population by the Genome Aggregation Database (gnomAD). 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV001339245 SCV001532975 uncertain significance Ehlers-Danlos syndrome, type 4 2020-10-27 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. 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. This variant has not been reported in the literature in individuals with COL3A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 927350). This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with arginine at codon 1425 of the COL3A1 protein (p.Ser1425Arg). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and arginine.
