Labcorp Genetics (formerly Invitae), Labcorp RCV003785363 SCV004604977 uncertain significance Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 2024-01-12 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1128 of the COL1A2 protein (p.Leu1128Phe). This variant is present in population databases (rs764382391, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with COL1A2-related conditions. 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 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.
