The purpose of this study is to investigate the association of IκBα with the development of ankylosing spondylitis (AS) in Taiwan. One hundred and fifty-four patients with AS and 112 unrelated healthy controls were enrolled in this study. The IκBα-881A/G, -826C/T, -550A/T, -519C/T, and -297C/T polymorphisms were determined by the polymerase chain reaction/restriction fragment length polymorphism method. This study demonstrated that the genotype frequencies of IκBα-826C/T and -826T/T, and allele frequencies of IκBα-826T were significantly higher in the patients with AS than in the controls. We also found that the estimated haplotype frequencies of IκBα-881A -826T -550A -519C -297C and IκBα-881A -826C -550A -519T -297C were significantly increased in the patient with AS in comparison with that of the controls. In contrast, the estimated haplotype frequency of IκBα-881A -826C -550A -519C -297C was significantly decreased in the patients with AS. This study demonstrates that IκBα-826T is associated with the development of AS. Furthermore, the IκBα-881A -826T -550A -519C -297C and IκBα-881A -826C -550A -519T -297C haplotypes are related to susceptibility to AS in Taiwan.

To investigate the role of IkappaBalpha promoter polymorphisms in the development of Behçet's disease, eighty-six patients with Behçet's disease and 120 healthy controls were enrolled in this study. The IkappaBalpha -881A/G, -826C/T, -550A/T, -519C/T, and -297C/T polymorphisms were measured by the method of polymerase chain reaction/ restriction fragment length polymorphism. This study demonstrated that the genotype frequencies of IkappaBalpha -826C/T and -826T/T were significantly higher in the patients with Behçet's disease than in the controls.

Introduction: To investigate the association of IkBalpha promoter polymorphisms with the development of primary Sjögren's syndrome in Taiwan, 98 patients with primary Sjögren's syndrome and 110 unrelated healthy controls were enrolled in this study.
Materials And Methods: The IkappaBalpha -881 A/G, IkappaBalpha -826 C/T, IkappaBalpha -550 A/T, IkappaBalpha -519 C/T, and IkappaBalpha -297 C/T polymorphisms were determined by the methods of polymerase chain reaction/restriction fragment length polymorphism.
Results: This study demonstrated that the genotype frequencies of IkappaBalpha -826 C/T and IkappaBalpha -826 T/T, in comparison with that of IkappaBalpha -826 C/C, were significantly higher in the patients with primary Sjögren's syndrome than in the controls.

To investigate the associations of IkappaBalpha gene polymorphisms with the development and clinical manifestations of systemic lupus erythematosus (SLE), 110 patients with SLE and 120 unrelated healthy controls were enrolled in this study. The IkappaBalpha -881 A/G, -826 C/T, -550 A/T, -519 C/T, and -297 C/T polymorphisms were determined by the polymerase chain reaction/reaction fragment length polymorphism method. The genotype frequency of IkappaBalpha -826 C/T in the patients with SLE was significantly higher than that of the controls (p = 0.
