Fig 1. Partial karyotypes of AML1/ETO-positive patients with variants of t(8;21). The rearrangements have been interpreted as (A) t(8;20;21)(q22;p11.2;q22) in patient no. 1; (B) t(8;10)(q22;q26) initially, and revised later to t(8;10;21)(q22;q26;q22) in patient no. 2; (C) t(1;10;8) (p22;p13;q22),del(21)(q22) initially, and revised later to t(1;10;21;8)(p22;p15;q22;q22) in patient no. 3; and (D) ins(8;21)(q22;q22q22) in patient no. 4. Arrows indicate breakpoints.
