Levels Of Antibodies Against Muscle-Specific Kinase Are Not Reflective Of Disease Severity In People With MuSK-Positive Myasthenia Gravis, Study Finds

Myasthenia Gravis News (4/29, Wexler) reports, “Levels of antibodies against muscle-specific kinase (MuSK) are not reflective of disease severity in people with MuSK-positive myasthenia gravis (MG), according to a study.” Investigators came to this conclusion after analyzing “749 blood samples collected from 641 people with MG over the course of at least 10 years,” with 21 of those samples coming “from seven patients” who “were positive for anti-MuSK autoantibodies.” The findings were published in the Journal of the Neurological Sciences.
