BTG3 and Schwartz-Jampel syndrome: Our work aims to combine the information collected in recent years regarding classic and novel autoantibodies in SjS, with a special emphasis on the role of ANA and the HEp-2 IIFA staining pattern, trying to define the usefulness of “organ-specific” biomarkers in the creation of new patient phenotypes that may step up the diagnosis of SjS in the future.
