Myotonic dystrophy type 2 (DM2) causes progressive muscle weakness, myotonia, variable muscle pain, cardiac conduction block, cataracts, and GI dysmotility. Here we utilize the National Registry and a longitudinal prospective study to characterize disease burden and progression in DM2. The National Registry provides up to 20 years of patient-reported follow-up on important disease milestones, such as the use of assistive devices, non-invasive ventilation, or implantable cardiac devices. The natural history study spans 3 years and provides comprehensive and quantified information on strength and function in people with DM2. To date, 39 participants with DM2 enrolled. Preliminary data on strength, function, and effects on the transcriptome will be presented.
