FHL1 and X-linked myopathy with postural muscle atrophy: Among these identified proteins were those which are known to play crucial roles in the etiopathology of other neuromuscular diseases; Fhl1 (fc = 2.88; p = 0.01), as a protein shuttling between the sarcoplasm and myonuclei, is involved in muscle development or hypertrophy, and mutations in the corresponding gene were linked to X-linked Emery-Dreifuss muscular dystrophy 6 (EDMD6; MIM: MIM:300696), X-linked dominant scapuloperoneal myopathy (SPM; MIM:300695) and X-linked myopathy with postural muscle atrophy (XMPMA; MIM:300696), respectively.
