Familial Sjögren's syndrome in the Japanese: immunogenetic and serological studies

Clinical and Experimental Rheumatology

Abstract

Serological abnormalities and HLA haplotypes were studied in a Japanese family of two patients with Sjögren's syndrome (SS) associated with other autoimmune diseases. In contrast to the reports in the U.S.A. and Europe, we found a significant excess of HLA-DRw53 antigen in the family members. Two family members, mother and niece of the probands, had suffered from other connective tissue diseases. Although none of the siblings of probands had manifestations of connective tissue diseases, two siblings had several autoantibodies. No consistent segregation, however, was found between the HLA haplotypes and the serological abnormalities in the relatives. Therefore, HLA alone can not explain the familial clustering of autoimmune diseases including SS and of autoantibodies.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
