RCV000389218 | SCV000428747 | likely benign | Collagen 6-related myopathy | 2018-01-12 | 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. |

RCV001372713 | SCV001569396 | pathogenic | Bethlem myopathy 1A | 2023-09-19 | criteria provided, single submitter | clinical testing | This variant is present in population databases (rs541928674, gnomAD 0.01%). For these reasons, this variant has been classified as Pathogenic. 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 expected to disrupt COL6A3 protein function. ClinVar contains an entry for this variant (Variation ID: 192264). This missense change has been observed in individual(s) with dystonia (PMID: 26004199; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 2501 of the COL6A3 protein (p.Arg2501His). |
