200 bp deletion in exon 6 (nucleotides 1271-1470).
Mutants die at pupal stage P3. Third instar latvr6.35/latlE344 larvae lack imaginal discs and show an undersized CNS, although the gross morphology of imaginal discs and CNS in second instar larvae appears normal. No BrdU incorporation is seen in third instar brains, reflecting lack of cell proliferation, whereas 2nd instar brains appear normal.
Decrement in 15-minute memory retention.
Orc3vr6.35 is rescued by Orc3+t17.1
Complementation statement based on recessive pupal lethality phenotype.
