Figure 6. The chromosomal positions of the three previously reported duplications (Chr20: 6,808,129–6,814,024; Chr20: 6,808,477–6,814,024; and Chr20: 6,809,382–6,814,044) are indicated by the horizontal arrows.

Comparison with the reported duplications shows that our duplication (Chr20: 6,809,218–6,813,888) overlaps with them but has different ends. Furthermore, the causal sequences of BDA2 could be narrowed down to 4,507 bp (Chr20: 6,809,382–6,813,888).
