Anti-Mi-2 Ab (RDL)
Also known as: Anti-Mi-2, Mi2
Use
Anti-Mi-2 antibodies are found in 10-20% of adult dermatomyositis (DM) and <10% of JDM. They are associated with classic DM features: mild to moderate weakness with shawl rash, heliotrope rash, V-sign, Gottron's papules, and have a good response to therapy, with lower incidence of cancer compared to Mi-2 negative DM.
