title: [Spondyloarthropathies and HLA-B27 subtypes in the populations of the Russian North].
abstract: The aim of the study was to investigate the role of HLA-B27 subtypes in development of ankylosing spondylitis and other seronegative spondylarthropathies. Using oligotyping techniques we studied native DNA of 219 HLA-B27 positive natives: 88 Chukotka residents and 131 Mordovians (Russian Ugro-Finnish population). Only subtypes HLA-B*2705 and B*2702 were revealed. A dominant subtype of HLA-B27 among the natives was HLA-B*2705: 99% among residents of Chukotka and 86% among Mordovians. It was established that among spondylarthropathic patients the frequency of B*2705 does not differ from its incidence in the studied populations. The data support the suggestion that several B27 subtypes and common genetic determinant of B27 gene may be involved in pathogenesis of spondylarthropathy.
