Other phenotypes in this spectrum are scapuloperoneal syndrome and congenital muscular dystrophy. (beds.ac.uk)

Based upon the subtype, the degree of limb weakness does not always correlate to the severity of respiratory weakness. (medscape.com)

It's an inherited disease which means genetic therapies might help. (bayer.com)
