In addition, abnormal IFI16 expression has been also detected in the skin of individuals affected by systemic sclerosis (SSc) [10] or psoriasis (Pso) [11–13], as well as in salivary epithelial cells and infiltrating lymphocytes of subjects with Sjögren’s syndrome (SS) [14,15]. This evidence concerns the gene IFI16 and synovial sarcoma.
