Frequencies of specific haplotypes in blocks 1 and 4 in Controls, BCP-ALL and T-ALL.

P values are the results of two-tailed Fisher's Exact tests comparing control with either BCP-ALL or T-ALL frequency; bold format indicates uncorrected PHLA-DPB1 alleles predicted by PHASE to be carried on each Block 4 haplotype are also shown (percentages in brackets indicate the proportion of each DPB1 allele predicted to be carried on the haplotype.
