On the cover: Genetic mapping of the polymorphism that determines expression level of IL2RA, the gene encoding the IL-2Rα subunit (CD25). The peak of association with IL2RA mRNA level coincides with one of the two peaks of diabetes association at IL2RA intron 1: the diabetes-predisposing allele directs lower levels of expression.
