title: HLA haplotypes and hayfever: a possible protective role.
abstract: The HLA haplotype frequencies of European asthmatic children and their immediate families were studied, and a disassociation between haplotype A1-B8 and skin sensitivity to grass pollens was found, suggesting that within this allergic population, possession of the haplotype A1-B8 conferred possible protection against grass pollinosis. There was no association between A1-B8 and clinical asthma or between it and skin sensitivity to the house dust mite.
