<i>CTLA4</i> 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.
