CRISPR-targeting of exon 4 produced 6 different alleles: a 12 bp deletion (#20-1(alle1)), a 78 bp deletion (#20-1(alle2)), a 7 bp deletion (#20-2(alle1)), a 56 bp deletion (#20-2(alle2)), a 12 bp deletion (#32-1) and a 3 bp deletion (#32-3). Line #20-2(alle2) with a 56 bp deletion was used as the representative line. (J:263251)
