AUTOIMMUNITY IN MYASTHENIA GRAVIS: A FAMILY STUDY.

This article describes the distribution of autoantibodies in the sera from thirty-two patients with myasthenia gravis and their relatives as well as in the sera of patients with a variety of other disorders. Additional evidence in support of the possibility that an autoimmune disturbance might be a factor in the pathogenesis of myasthenia gravis might be obtained by examining its association both clinically and serologically with other putative autoimmune diseases. Since autoimmune diseases frequently run in families, a similar study of the relatives of patients with myasthenia gravis would be of interest.
