Invitae RCV000146473 SCV001201848 pathogenic Severe X-linked myotubular myopathy 2019-12-27 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg222*) in the MTM1 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals affected with myotubular myopathy (PMID: 9305655, 26338224, 12522554). ClinVar contains an entry for this variant (Variation ID: 158994). Loss-of-function variants in MTM1 are known to be pathogenic (PMID: 9305655, 10063835). For these reasons, this variant has been classified as Pathogenic.
