G to A nucleotide change at the second or third position of the Trp codon leads to a nonsense mutation (exact site of mutation unspecified). Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Lethality occurs before the wandering third larval instar stage in homozygotes.
Homozygous clones in the third larval instar brain consist of only a few cells. Neuroblasts in the clone appear to be arrested n a metaphase-like state with condensed chromosomes, but no clear metaphase plate.
