Myositis Specific Antibodies (MSAs): What Families Need to Know

Myositis-specific antibodies (MSAs) are associated with certain symptoms in JM patients. In some cases, knowing the MSA of a patient may help clinicians look out for certain symptoms and guide treatment decisions. Dr. Jessica Neely explains these associations, why they are important, and the limitations in our understanding of the role of MSAs in JM.
