Figure 2.
HLA allele linkage distributions of HLA-A, -C, -B, -DRB1, -DQA1, -DQB1, and -DPB1 in Japanese PBC. The heights of the bars show the number of samples carrying the particular HLA alleles, and grey lines connecting orange bars indicate the proportion of linkage between different orange bars. Susceptible and protective HLA haplotypes are highlighted in magenta and yellow, respectively.
