According to Wikipedia, dermatomyositis is associated with autoantibodies, especially antinuclear antibodies (ANA). Around 80% of people with DM test positive for ANA. Around 30% of people have myositis-specific autoantibodies which include:
  • Ÿ antibodies to aminoacyl-tRNA synthetases (anti-synthetase antibodies), antibodies against  histidine—tRNA ligase (also called Jo-1);
  • Ÿantibodies to signal recognition particle (SRP);
  • Ÿanti-Mi-2 antibodies.
