Immunoglobulin allotypes (GM and KM) in Basques from Spain: approach to the origin of the Basque population.

abstract：:HLA-DQB1*0302 allele frequency is increased in liver graft recipients with acute rejection. We investigated polymorphism in the upstream regulatory regions (URRs) of the DQB1 gene to determine whether polymorphism in the DQB1 promoter region influences liver graft acceptance.
