Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Homozygous neuroblast clones result in a 20% reduction in the number of projection neurons compared to wild type. Their dendrites appear to target normally.
Homozygous single-cell DL1 projection neuron clones show normal dendrite targeting and normal axon arborisation in the lateral horn.
At 29oC, Hdac3N/+ enhances the ectopic wing vein phenotype of Snr1E1/+; 100% of flies have ectopic veins emanating from the posterior crossvein and posterior to the L5 longitudinal vein. The ectopic wing vein phenotype seen in Hdac3N/Snr1E1 double heterozygotes at 29oC is partially suppressed by brm2/+.
