Invitae RCV001067599 SCV001232667 uncertain significance Bethlem myopathy 1 2022-07-06 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. This variant disrupts the C-terminus of the COL6A1 protein. Other variant(s) that disrupt this region (p.Leu941Alafs*34) have been observed in individuals with COL6A1-related conditions (PMID: 33250842). This suggests that this may be a clinically significant region of the protein. ClinVar contains an entry for this variant (Variation ID: 861146). This premature translational stop signal has been observed in individual(s) with clinical features of type VI collagenopathy (Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Cys810*) in the COL6A1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 219 amino acid(s) of the COL6A1 protein.
