Muscular dystrophy can mimic inflammatory myopathies like polymyositis. A type of limb-girdle muscular dystrophy, LGMD2B, is especially prone to misdiagnosis as PM. It is very important to pursue a correct diagnosis to avoid the side effects of ineffective treatment which can include non-recoverable loss of strength. TMA is working with the Jain Foundation, an organization focused on a cure for LGMD2B, to help those who may be misdiagnosed. Please visit the Jain Foundation website to learn more.
