Local hop that removes the progenitor P{lacW}k07406 insertion. Homozygotes also fail to PCR amplify CG43324 using primers that are 17bp upstream of P{EP}G7530 to 289bp downstream of P{EP}G7530 or to a 2nd overlapping primer pair (a 340bp fragment beginning 112 nt downstream of P{EP}G7530).
Lethal. Cell lethal by clonal analysis.
