Limb-girdle muscular dystrophy (LGMD) type 2I, caused by mutations in the fukutin-related protein gene (FKRP), is one of the most common forms of LGMD in childhood. We describe two patients with LGMD2I and a Duchenne-like phenotype. In addition to the common L276I mutation, both patients had a new mutation in FKRP, L169P and P89L, respectively. Clinical onset was triggered by viral upper respiratory tract infections. In addition to the common dystrophic pattern with a weak immune histochemical staining for alpha-dystroglycan, muscle biopsy showed inflammatory changes. This was especially striking in one of the patients with up-regulation of MHC class 1 antigen, suggestive of myositis. Both patients showed a good clinical response to treatment with prednisolone, which was initiated at daily dosage of 0.35 mg/kg/day. Our results provide evidence for an inflammatory involvement in the pathological expression of LGMD2I and open up the possibility that this disorder could be treatable with corticosteroids.
