Invitae RCV001053984 SCV001218275 pathogenic Bethlem myopathy 1 2019-12-30 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in COL6A2 are known to be pathogenic (PMID: 19884007, 20976770). In addition, donor and acceptor splice site variants in COL6A2 that result in in-frame exon skipping have also been reported to cause autosomal dominant COL6A2-related conditions (PMID: 18366090). This variant has been observed in an individual with clinical features of type VI collagenopathy (Invitae). In this individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 3 of the COL6A2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
