Genome editing technologies like CRISPR-Cas9 have transformed biology, medicine, and agriculture, but concerns remain about unintended edits at off-target DNA sites. These off-target effects can cause harmful mutations and are difficult to predict, as they depend not only on the guide RNA but also on an organism's unique genetic makeup. Most existing prediction tools rely on a standard reference genome, ignoring key variations like SNPs, insertions, and deletions that differ across individuals and alleles.
