a A short direct repeat (DR) was considered as starting from the deletion breakpoint and was extended if the bases in the 5′ and 3′ flanking sequences matched, or if a single-base mismatch was followed by at least two matching bases. The DR was considered as stopping where a mismatch was followed by zero or one matching base
