Invitae RCV001232954 SCV001405530 likely pathogenic Bethlem myopathy 1 2019-09-06 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 8 of the COL6A1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with COL6A1-related conditions. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in COL6A1 are known to be pathogenic (PMID: 21280092, 20976770). In addition, donor and acceptor splice site variants in COL6A1 that result in in-frame exon skipping have also been reported to cause autosomal dominant COL6A1-related conditions (PMID:18366090). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
