Intercellular adhesion molecule-1 gene polymorphisms in isolated polymyalgia rheumatica.

Abstract

Although ICAM-1 polymorphisms alone do not appear to be associated with disease severity in isolated PMR, the presence of both HLA-DRB1*0401 and the ICAM-1 codon 241 GG homozygosity was significantly associated with increased risk of relapses in these patients.
