RCV001143312 | SCV001303827 | likely benign | Collagen 6-related myopathy | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. |
| Invitae | RCV001882441 | SCV002302220 | uncertain significance | Bethlem myopathy 1 | 2023-01-05 | 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 COL6A2 protein function. ClinVar contains an entry for this variant (Variation ID: 899068). This variant has not been reported in the literature in individuals affected with COL6A2-related conditions. This variant is present in population databases (rs368588676, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 366 of the COL6A2 protein (p.Arg366Gln). |
| Ambry Genetics | RCV003346334 | SCV004066710 | likely benign | Inborn genetic diseases | 2023-08-08 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
