International GNE Myopathy Patient Registry

GNE myopathy, an ultra-rare disease, is a severe progressive myopathy that typically presents in early adulthood as weakness in the distal muscles of the lower extremities and progresses proximally, leading to a loss of muscle strength and function, and ultimately a wheelchair-bound state. The rate of progression is gradual and variable over the course of 10-20 years or longer. There is a need to understand the world wide epidemiology of this ultra-rare condition, better understand a long-term disease course and the progression of disease-specific features, support translational research by evaluating burden illness and support clinical research recruitment. Therefore, the study will longitudinally collect information via an online patient registry platform.

Inclusion Criteria: * Aged 18 years or older at the time of informed consent * Clinical and/or genetic diagnosis of GNE myopathy (also known as HIBM, QSM, Inclusion Body Myopathy Type 2, DMRV, or Nonaka disease) * Willing and able to provided electronic (or written) consent and comply with all study requirements. Exclusion Criteria: * Under 18 years of age
