31bp deletion associated with an imperfect 12bp duplication at one end of the deletion in the coding region in exon 1. This results in a stop codon in place of amino acid residue 9.
ref(2)Pod2/ref(2)Pod3 mutant midgut cells at 2hr after puparium formation show similar amount of mitochondria as in controls.
Embryos derived from ref(2)Pod2/ref(2)Pod3 females show a moderate delay in the clearance of the paternal mitochondrial derivatives compared to wild type.
Early onion-stage spermatids of mutant males have abnormal nebenkern (mitochondrial derivatives) which envelop the white nuclei instead of being adjacent to them. The mutant spermatids undergo normal elongation, but individualisation is abnormal. There is an increased distance between the axoneme and mitochondrial derivative than normal in post-individualisation cysts, and the mitochondrial derivative contains a large mass of electron-dense material.
The density of mitochondrial DNA nucleoids in the indirect flight muscle is increased in mutant flies compared to wild type.
Mutants show an increase in mitochondrial DNA heteroplasmy compared to wild type in both 3 day old and 25 day old adults.
Mutant animals show a decrease in lifespan compared to wild type, both on normal food, or on food supplemented with either rotenone or paraquat. Locomotor activity is impaired from a young age and progresses with age.
Mutants show mitochondrial defects in the indirect flight muscles.

ref(2)Pod2 is a non-suppressor of melanotic mass phenotype | recessive | third instar larval stage phenotype of Atg61
ref(2)Pod2 is a suppressor of mitochondrion phenotype of Pink1B9
ref(2)Pod2 is a suppressor of indirect flight muscle cell phenotype of Pink1B9
ref(2)Pod2 fails to suppress the melanotic mass phenotype seen in Atg61 mutant third instar larvae.
The mitochondrial clustering seen in the indirect flight muscles of Pink1B9 flies is significantly suppressed by ref(2)Pod2.
Expression of parkScer\UAS.cGa under the control of Scer\GAL4da.G32 significantly suppresses the penetrance of the indented thorax phenotype seen in Pink1B9 mutants. This suppression is reduced if the flies are also carrying ref(2)Pod2.
