RCV001760694 | SCV001990439 | uncertain significance | not provided | 2019-07-19 | criteria provided, single submitter | clinical testing | Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Occurs in the triple helical domain at the X position in the canonical Gly-X-Y repeat. Although this variant may have an effect on normal protein folding and function, missense substitution at the X position is not a common mechanism of disease (Stenson et al., 2014) |
| Invitae | RCV002032871 | SCV002290241 | uncertain significance | Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 | 2022-03-02 | 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 COL1A2 protein function. ClinVar contains an entry for this variant (Variation ID: 1307276). This variant has not been reported in the literature in individuals affected with COL1A2-related conditions. This variant is present in population databases (rs770180852, gnomAD 0.004%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 110 of the COL1A2 protein (p.Pro110Leu). |
