Somatic mutations of HLA-B*40:02 in 15 patients with AA. (A) The kinds and VAFs of somatic mutation in individual patients identified in B4002⁻A⁺ (upper graph) and B4002⁺A⁺ (lower graph) granulocytes are shown. The kinds of mutations are designated in different colors. (B) The positions of all somatic mutations in the HLA-B*40:02 region are shown. The color and shape of each symbol correspond to those of panel A.
