Figure 1.
Allele/haplotype frequencies of interleukin 10 (IL-10), tumour necrosis factor A (TNF-A), and interferon G (IFN-G) polymorphisms. Single nucleotide polymorphisms (SNPs) at positions −819 and −592 in the IL-10 promoter were in complete linkage disequilibrium (LD). Four IL-10 haplotypes were observed and the occurrence of each haplotype and of haplotype combinations are listed in the shaded boxes.
