Breakpoints on the MLL and MLLT3 genes. (A) MLL gene on chromosome 11. (B) MLLT3 gene on chromosome 9. The MLL and MLLT3 genes had a breakpoint in their gene regions. Weighted log ratio data appear as a scatter plot. Red points represent suprathreshold values. The identified aberrant region is plotted as a bar graph shaded in red, and height of each bar corresponds to the average log ratio for that interval.
