Figure 3. Breakpoint regions of cases 3, 4, and 5 contain Alu elements.

Deletion breakpoints in cases 3 (A), 4 (B), and 5 (C) are located within clusters of Alu elements. Deleted region in each case is indicated by the solid red bar; the dotted bar indicates the breakpoint region as determined by the region between the last deleted probe and the next probe with normal log₂ ratio. In each case, the breakpoint region is within a cluster of Alu elements.
