CTLA4 haplotype frequencies in TB cases stratified for the sizes of opacities and cavities in chest radiographs1.

1Seven tagging SNPs reported to appropriately indicate CTLA4 haplotypes in sub-Saharan Africans (Ref. 13) analysed by the Haplo.score software assuming a recessive mode of inheritance.2P values obtained testing an overall association between haplotypes and the phenotype.3Global P values corrected for multiple testing by 20,000 permutations.4Frequency; only haplotypes with a frequency>0.01 are shown.5P values of haplotype-specific associations.6Simulated haplotype-specific P values corrected for multiple testing by 20,000 permutations.7Score statistic of the haplo.score software.
