Genotyping of the HLA-C locus by PCR-SSP in Behcet's disease patients
from southern Spain reveals a statistically significant association wi
th Cw1602 (OR 20.15, corrected p < 0.05). This is an uncommon allele
absent from the healthy control group, which seems to confer higher re
lative risk than B51 in this study (OR 1.85), Stratified frequencies d
o not show statistically significant differences but suggest that the
Cw1602-B51 haplotype could be the main HLA marker of Behcet's disease
in the analyzed population.
