Sjögren's syndrome (SS) is a chronic autoimmune disease with a genetic component. Among the genetic factors, the role of HLA class II genes has been suggested and a positive association with DRB1*03 allele has been described. However, there is no consensus on a unique HLA locus for this disease nor on the role of the HLA gene product in the disease. The aim of this study was to analyse prospectively MHC region involvement in the genetic susceptibility to SS by studying DRB1, DQB1, DPB1, TAP1, TAP2 genes and TNF microsatellites in a population of 45 primary SS patients.
