FSHD research continues to move forward with the generous help from the Friends of FSH Research. Dr Dan Miller at the University of Washington’s Institute for Stem Cell and Regenerative Medicine, and Dr. Stephen Tapscott at the Fred Hutchinson Cancer Research Center think that one possible cause of muscle weakness in FSHD is a defect in the generation of muscle tissue that may start before birth, and persist as muscles are continually modified and repaired throughout life.
