Non-HLA gene polymorphisms in juvenile rheumatoid arthritis.
Rosen P, Thompson S, Glass D
Clin Exp Rheumatol. 2003;21(5):650.
A substantial amount of work has gone into elucidating the non-HLA genetic associations in JRA. In this paper, we attempt to provide an overview of this body of knowledge. Direct comparison of the different studies is difficult. Different ethnic populations, different JRA/JIA subgroups, and different systems of nomenclature and classification all impose various limitations. Adding to the complexity is the polygenic nature of chronic childhood arthritis. Family based studies will be necessary to overcome ethnicity related issues. A candidate gene approach complemented by genome wide screen data will hopefully advance our knowledge of the genetics of JRA.
