||SRP is considered a Myositis-specific antibody. It is commonly found in Polymyositis, ILD and arthritis, and occasionally in dermatomyositis. Anti-SRP was first described in a polymyositis patient in 1986. Anti-SRP antibodies are rare, in only about 4% of myositis patients, and are often found in African American females with an acute, severe onset of polymyositis, with poor response to therapy.
