Two of the 36 SNPs that were found to be moderately associated with having TB in a previous genome-wide association study (GWAS) are located in or proximal to regions identified in this study [9] (rs6694316 on 1p32 which is 16 cM way from the first SNP in the identified 1p31 region, that harbours the GADD45A gene, and rs4745272 on 9q21). This evidence concerns the gene GADD45A and tuberculosis.
