Methods of using IL-21

摘要

An allelic variation in the IL-21 receptor can result in reduced IFN-γ production in individuals and can require administration of different doses of IL-21 to achieve therapeutic effects seen individuals that do not have the allelic variant. Based on the genotype of a patient's IL-21 receptor allele, methods of predicting therapeutic response to treatment with IL-21 are disclosed. Also disclosed are methods of selecting a therapeutic regimen for use of IL-21 in patients with variant IL-21 receptor alleles.
