Recombination between the two progenitor insertions has resulted in the deletion of the intervening sequence between them, producing a 49.7kb deletion that completely removes LpR1 and removes exons 1 to 8 of LpR2.
Deletion of LpR1 and LpR2 resulting from FLP-catalyzed recombination using the FRT-containing transposons P{XP}d10508 and PBac{RB}LpR2e00374.
