Rippling muscle disease with myasthenia gravis

Definition

Rippling muscle disease with myasthenia gravis is a rare, acquired, neuromuscular disease characterized by CAV3 mutation-negative rippling muscle disease in association with acetylcholine receptor antibody-mediated myasthenia gravis. Patients typically present exercise-induced, electrically-silent muscle rippling with myalgia, in combination with generalized myasthenia gravis symptoms (ptosis, diplopia, neck weakness, dysphagia and dyspnea).
