A 6400 bp long deletion starting with the sequence 5'-GATGCCTTTGTTGCCGCCCT-3' and ending with the sequence 5'-GTATGAACTTCTCTCACGGC-3' ( 3R:22373250...22368775 ; based on the D. melanogaster reference genome release 6.53), and includes an 18-bp insertion of the sequence 5'-AAGTTCAAGTTCTGGATT-3'. It deletes the entire Pyk-coding region as well as the first-coding exons of both the upstream and downstream neighboring genes (Polr3F and CG7069).
