Antibodies against PM/Scl-75 and PM/Scl-100 are independent markers for different subsets of systemic sclerosis patients. Anti-PM/Scl antibodies are common in distinct SSc subsets and are associated with several clinical symptoms. They are mainly directed to the PM/Scl-75 antigen. Consequently, the detection of anti-PM/Scl antibodies by tests based only on PM/Scl-100 as antigen source may miss a relevant number of SSc patients positive for these antibodies. K. Hanke.
