Map of the CTLA4 gene region and the SNPs typed. Genes (CD28, CTLA4 and ICOS) are represented by gray boxes, CTLA4 exons by black boxes and SNPs are represented by vertical tick marks. (a) Allelic variants found in the worldwide human population set and ancestral states deduced from primate genotyping. (b) Suggested tag-SNPs for different geographical populations.
