Note: The amounts of different complex deletion and their corresponding formation mechanisms.

^aDeletion with insertion at the break point with unknown source.

^bDeletion with insertion at the break point, insertion comes from a different chromosome, opposite orientation.

^cDeletion with insertion at the break point, insertion comes from the same chromosome, opposite orientation and downstream of deletion.

^dDeletion with insertion at the break point, insertion comes from the same chromosome, opposite orientation and upstream of deletion.

^eDeletion with insertion at the break point, insertion comes from the same chromosome, same orientation and downstream of deletion.

^fDeletion with insertion at the break point, insertion comes from the same chromosome, same orientation and upstream of deletion.

^gDeletion with inversion at the break point, inversion comes from deleted part.
