“The incidence of the tissue antigen HLA-B27 has been studied in 176 consecutive blood donors in Tromsø, Northern Norway.
The prevalence of HLA-B27 was 15.9%, which was significantly higher than that found in Southern Norway (10%).
The frequency of 15.9% is comparable to the prevalence of this antigen found in Northern Sweden (16.6%) and Finland (14–16%).”
