HLA B-27 Subtypes in Turkish Patients with Spondyloarthropathy and Healthy Controls

[摘要] The frequency and the distribution of HLA-B27 subtypes in spondylarthropathy (SpA) patients and controls were investigated in a sample Turkish population. B27 subtyping was performed by PCR-SSP method in two groups: 49 unrelated HLA-B27 positive Turkish patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group Criteria, and 55 HLA-B27 positive healthy controls. The frequency of HLA-B∗27 was 2.6% in the Turkish population, and B∗2705 was the predominant allele among patients with SpA. The difference was mainly between male patients and male controls The proportion of B∗2705 among B27-positive patients and controls was significantly different (P= 0.02). Our study supports other reports from different populations which showed that B∗2705 and B∗2702 were more frequent in Caucasian patients with SpA.
