Centre for Mendelian Genomics, University Medical Centre Ljubljana RCV001198482 SCV001369429 uncertain significance Bethlem myopathy 2 2019-08-13 criteria provided, single submitter clinical testing This variant was classified as: Uncertain significance. The available evidence on this variant's pathogenicity is insufficient or conflicting. The following ACMG criteria were applied in classifying this variant: BP4.
Labcorp Genetics (formerly Invitae), Labcorp RCV001863127 SCV002267899 uncertain significance Ullrich congenital muscular dystrophy 2; Bethlem myopathy 2 2023-04-04 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 951 of the COL12A1 protein (p.Lys951Glu). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with COL12A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 931671). 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 COL12A1 protein function. 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.
