title: [DNA typing of allelic variants of HLA-B27: HLA-B*2705 is the predominant allele of the aboriginal population of the Chukot peninsula (Eskimos and Chukchi)].
abstract: The purpose of the study was to estimate the relative frequency of the known HLA-B27 subtypes among HLA-B27 positive Chukot natives. Using oligotyping of the polymerase chain reaction amplified second and third exons of the HLA-B27 gene in 86 DNA samples from HLA-27 positive individuals were success-fully typed. All had HLA-B*2705, including nine patients with ankylosing spondylitis and Reiter's syndrome, except for one Eskimo who had HLA-B*2702. None had HLA-B*2704, a frequent subtype in Orientals. Considering the HLA-B27 subtypes, the Chukot population groups are genetically more closely related to Caucasians than to Orientals.
