(A) Schematic representation of haplotypes previously defined by Gonzalez et al. (1999) and the frequency at which they were detected within our two study populations. (B) Haplotypes identified within the CCR5 gene in the SAA and SAC study populations. Haplotypes were named by prefixing the root haplotype with the population within which it was found. Polymorphic positions as well as the wild type (WT) to mutant change are shown. Coloured boxes indicate SNPs or indels which form part of the haplotype and the frequency of occurrence in that particular population group is indicated. The root haplotype (Gonzalez et al., 1999) is also indicated.
