About

This is a prospective, longitudinal study of the natural disease course intended to recruit approximately 60 patients with centronuclear myopathies (CNM) in Europe and the United States. The duration of the study, including the enrollment period, will be approximately 4 years. Data from the study will be used to characterize the natural disease course of CNM, to identify prognostic variables of the disease and to determine the best outcome measure(s) for the evaluation of future therapeutic approaches.
