Granulomatosis with polyangiitis (GPA) is a rare autoimmune systemic vasculitis considered to result from the interaction of environmental factors with a genetically predisposed host. The HLA-DPB1*0401 allele, the PI*Z allele of the gene encoding α1-antitrypsin (SERPINA1) and the proteinase 3 (PRTN3) gene have been associated with GPA. The incidence of GPA is lower in non-Caucasian populations and has been associated with higher latitude. Our aim was to determine whether variation in population carrier frequency of the HLA-DPB1*0401 and PI*Z alleles could explain in part the variation in GPA incidence between countries.
