Sjögren syndrome type A antigen (SS-A) are autoantibodies that are regarded as antinuclear antibody (ANA) which essentially targeting the nucleic acids in the cell cytoplasm rather than the cell nucleus. This is in contrast to standard ANAs which tend to target nucleic acids in the cell nucleus, for this reason individuals having ANA-negative systemic lupus are found to frequently have anti-SSA antibodies.
