Figure 1. The region of 22q11 containing LCR-A–LCR-H is shown.
A schematic diagram of proximal chromosome 22 indicating the position of the low copy repeats (LCRs) in 22q11.2. Boxes indicate the position of the LCRs. The bracket is indicates the recurrent 3Mb deletion of chromosome 22q11.2. The translocation breakpoint region on chromosome 22 is located within one of the remaining unclonable gap region from human genome project.
