Utah Researchers Seek CMD Families

Families affected by Ullrich congenital MD or Bethlem myopathy are invited to help with data collection at the University of Utah

Article Highlights:


  • A database is being created at the University of Utah to correlate genetic and clinical information in two forms of congenital muscular dystrophy, Ullrich CMD and Bethlem myopathy.

  • Families with these disorders are invited to participate.

  • Both diseases are caused by mutations in genes that affect the collagen 6 protein.

  • MDA is supporting pediatric neurologist Russell Butterfield to coordinate the project.

Families affected by either of two forms of congenital muscular dystrophy (CMD), known as Ullrich CMD and Bethlem myopathy, are invited to help with an MDA-supported data collection project at the University of Utah in Salt Lake City. The project's investigators are seeking to correlate genetic and clinical (symptom-related) information to improve understanding of these diseases and begin to develop treatments.


About Ullrich CMD and Bethlem myopathy


Both Ullrich CMD and Bethlem myopathy cause weakness, joint contractures or overly flexible joints, and skin changes, and both result from deficiencies or abnormalities of a protein called collagen 6.


Until recently, it was believed that Ullrich CMD and Bethlem myopathy were distinct disorders, but it's now known that they both arise from mutations in any of the three collagen 6 genes: COL6A1 on chromosome 21; COL6A2 on chromosome 21; or COL6A3 on chromosome 2.


Bethlem myopathy is less severe than Ullrich CMD. Both are considered congenital muscular dystrophies in MDA's classification system.


About the new project


Pediatric neurologist Russell Butterfield at the University of Utah School of Medicine in Salt Lake City has MDA support to oversee the establishment of a database containing detailed genetic and clinical information from people with collagen 6 abnormalities and Ullrich or Bethlem types of CMD.


The study will collect medical information from patients and from their medical records. There is no cost to families and no need to visit the researchers in Utah.


The investigators hope to:



  • gain a better understanding of the variation in the severity of symptoms and progression in these disorders;

  • develop testable hypotheses about their molecular underpinnings;

  • identify groups of patients who may become candidates for future clinical trials; and

  • encourage interactions among patients, families and researchers.
