Figure 4From: EVI1activation in blast crisis CML due to juxtaposition to the rare 17q22 partner region as part of a 4-way variant translocation t(9;22) Schematic representation of possible generation of the 4-way t(3;9;17;22). (A) Formation of the t(9;22)(q34, q11). (B) Three-way translocation involving the EVI1 locus on 3q26, part of the distal long arm of chromosome 17 and the der(9)t(9;22). (C) Representation of the derivative chromosomes 3, 9, 17 and 22 in our patient.Back to article page
