title: Lack of association of T cell receptor V beta 8 polymorphism with rheumatoid arthritis in United Kingdom and Italian white patients.
abstract: OBJECTIVE
  To study if the reported association of a BamH I 2kb RFLP of the T cell receptor V beta 8 gene with DR4+ rheumatoid arthritis patients is found in non-American white populations.
  
  
  METHODS
  The frequency of this RFLP in two different populations was analysed. Eighty one northern Italians were studied for HLA-DR genotypes and V beta 8 polymorphism, and 29 DR4+ British white patients were studied for V beta 8 polymorphism.
  
  
  RESULTS
  No association between the V beta 8 RFLP and DR4 was found with rheumatoid arthritis in both groups.
  
  
  CONCLUSIONS
  The reported V beta 8-DR4 association is not generally applicable. The lack of association in our populations may be due to genetic differences, or to differences in factors which shaped the T cell repertoire.
