Abstract

Tumor necrosis factor (TNF)-α and TNF-β are proinflammatory cytokines that have been implicated in the pathogenesis of several autoimmune diseases. The aim of this investigation was to determine whether a determinant in the first intron of the TNF-β gene (TNF-β+252) and two promoter-region polymorphisms of the TNF-α gene (TNF-α-308 and TNF-α-238) affect susceptibility to multiple sclerosis (MS). DNA samples from 133 Caucasian MS patients and 148 healthy controls from Norway were genotyped for several polymorphic determinants, using polymerase chain reaction-based restriction fragment length polymorphisms (PCR-RFLP) methods. TNF-β+252 genotypes were significantly associated with MS: The frequency of TNF-β 2,2 was increased (p = 0.00009) while the frequency of TNF-β 1,2 was decreased (p = 0.0012) in MS patients as compared to controls. TNF-α genotypes were not associated with MS. These results suggest that the TNF-β gene plays a significant role in the etiopathogenesis of MS.
