Mutants show age-related retinal degeneration with severe reduction in rhabdomeres at two weeks of age.
Flies carrying rdgH2-4388 over a non-complementing deletion have brick red eyes.
The retinal degeneration mutation represented by rdgH2-4388 likely corresponds to a loss-of-function mutation in Patsas, since sequencing of this gene in the '2-4388' mutant line reveals a mutation in the coding region (represented by Patsas2-4388).
