Labcorp Genetics (formerly Invitae), Labcorp RCV002587934 SCV003489820 uncertain significance Ehlers-Danlos syndrome, type 4 2023-12-18 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1207 of the COL3A1 protein (p.Gly1207Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with COL3A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2174508). 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 with a negative 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.
All of Us Research Program, National Institutes of Health RCV002587934 SCV005427383 uncertain significance Ehlers-Danlos syndrome, type 4 2024-08-13 criteria provided, single submitter clinical testing This missense variant replaces glycine with arginine at codon 1207 of the COL3A1 protein. Computational prediction tools indicate that this variant has a neutral impact on protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with COL3A1-related disorders in the literature. This variant has not been identified 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.
