Imprecise excision of the progenitor insertion, resulting in a deletion of 831bp which removes part of CG4476 (the deletion is predicted to remove only 19 amino acid residues at the extreme N-terminus but does not disrupt any of the transmembrane domains).
An 831bp deletion resulting from the imprecise excsion of P{XP}CG4476d11470, which extends from the insertion site into CG4476 and removes the first 19 amino acids.
Mutants have no evident morphological eye defects or obvious behavioural deficits.
Mutant flies show a normal response in a fast phototaxis assay.
