Recent advances in the genetics of autoimmune diseases

Autoimmune diseases in general are complex genetic diseases where genes and environment interact in unknown ways. In recent years technologies have advanced our knowledge and new genes are being identified very rapidly. We can expect that most genes of major importance for the various autoimmune diseases will be discovered in the coming 5 years. The real challenge comes when we try to understand the mechanisms through which these genes confer disease susceptibility and how the interaction with environment takes place such that clinical expression of the disease results.
