Imprecise excision of the progenitor insertion, which results in a deletion that removes part of the first intron and second exon of Acf1. The deletion is predicted to cause a frameshift after amino acid residue 41.
A 799 bp deletion resulting from the excision of P{EP}AcfEP1181 including 500 bp of the 2nd exon of Acf1; The deletion leads to a frame shift after the 41st residue with a stop codon occurring at the very beginning of the 3rd exon of Acf1.
Acf[+]/Acf5, Iswi2/Iswi1 has abnormal developmental rate phenotype
