title: Extractable nuclear antigen autoantibodies and their association with other autoantibodies and thymoma in myasthenia gravis.
abstract: The presence of autoantibodies to Extractable Nuclear Antigens (ENA) in myasthenia gravis (MG) was evaluated. These antibodies represent a subset of antinuclear antibodies (ANA), with ENA consisting of RNA and nucleoprotein. ENA autoantibodies had a prevalence of 44% in MG when tested by an
