Figure 2.

Precise mapping of novel variants and extended sequences per allele, by HLA gene. Novel alleles are numbered consecutively as shown on the y-axis, separated by locus and correspond to the allele numbering used in Supplemental Table 1. The position of the variant is relative to the start of exon 1. Exonic regions have the background shaded a darker gray. For hybrid alleles, the region where the recombination is believed to occur is indicated in green. A) HLA-A B) HLA-B C) HLA-C D) HLA-DPA1 E) HLA-DQA1 F) HLA-DQB1.
