Imprecise excision of the progenitor insertion, resulting in a 2357bp deletion which removes the entire Gr93a coding region (the deletion extends from 365bp upstream of the start codon to the site of the original insertion).
2357bp deletion resulting from the imprecise excision of P{EPgy2}Gr93aEY11817 removes sequences from 365 bp upstream of the Gr93a ATG to the insertion site.
