Abstract

Whereas TNF-α has been implicated in the pathogenesis of IDDM, its possible role as a primary genetic susceptibility factor has not been well investigated. In this study, we analyzed a biallelic polymorphism in the TNF- α promotor region in a large collection of IDDM patients and controls ascertained from two ethnic populations (U.S. Caucasians and Chinese in Taiwan). We report that the associations with TNF-α are due to linkage disequilibrium between TNF-α and the DR3-DQB1*0201 haplotype in both ethnic populations. Our analyses of extended haplotypes for the HLA region further substantiate the conclusion that no primary association exists between IDDM and the TNF-α promoter polymorphism.
