JIA is a complex genetic condition and the genes that influence susceptibility are actively being sought. A candidate gene approach is being used by several groups. MHC- cytokine- and T-cell-related genes have all been positively associated with JIA. Here we review some of the latest genetic data and discuss ways in which JIA genetic research might proceed. Keywords candidate genes cytokines genetics juvenile idiopathic arthritis Introduction It is necessary to define the genetic component of any disease in order to enhance the understanding of its pathogenesis imply its aetiology and refine its treatment. The most rapid progress towards such aims is best achieved when there is homology of the expressed form phenotype . Unfortunately progress in defining the genetic components of childhood arthritis has long proven difficult for two reasons. Firstly childhood inflammatory arthritis is not a single disease but a group of clinical syndromes. Secondly since its first description in the late 1890s classification of the chronic arthritides of childhood has been problematic. Ansell and Bywaters 1 first proposed that classification should be based on the characteristics of disease at onset and this basic premise still remains. This premise has led to the development of two .
