The registry has been developed in partnership with a number of leading neuromuscular researchers and is funded by the Collagen VI Alliance. This patient registry will: * Help identify patients for relevant clinical trials as they become available * Encourage further research into Collagen 6-related dystrophies * Provide researchers with specific patient information to support their research * Assist doctors and other health professionals by providing them with up-to-date information on managing Collagen 6- related dystrophies, to help them deliver better standards of care for their patients The investigators welcome the registration of: ✓ All patients, with a diagnosis of a COL6-related dystrophy (Bethlem Myopathy, Ullrich Congenital Muscular Dystrophy or Intermediate form) , which has been confirmed via genetic testing or muscle biopsy.
