ResumoAbstract: A polymerase chain reaction‐sequence‐specific primer (PCR‐SSP) method which distinguishes all B27 alleles described at present (B*2701–23) has been developed. The distribution of B27 alleles was characterised in six different Asian populations. HLA‐B*2705, 02, 04, 07, 22 (formerly B*2706) subtypes found in Asian populations differ in their ethnic distribution, which may be the result of different genetic and geographic origins. Furthermore, two novel B27 alleles were found in this study. B*2714 was identified in two Siberians, one of whom was a patient with ankylosing spondylitis. B*2715 was found in two patients with ankylosing spondylitis in Thais. These associations have not previously been reported in either ethnic group.
