Narrow wings with short connecting extra veins between LIII and LIV.
Some cells from the embryonic central nervous system are missing in the thoracic region in homozygotes.
fuJ has phenotype, non-suppressible by Pka-C1k11302/Pka-C1k08918
fuJ; ptcG20/ptc16 or fuJ; ptcG20/ptc4 flies are viable and show a fu phenotype, and the ptc phenotype is rescued, although occasionally incompletely. Partially rescues the phenotype produced by ectopic expression of hhScer\UAS.cCa using Scer\GAL4C-335a. fuJ; Pka-C1Cos-2 cosV1/cosV5 flies show a cos phenotype in the thorax and legs. Does not alter the wing and leg phenotypes of ciD/ciW flies. fuJ; Pka-C1k11302/Pka-C1k08918 flies show no suppression of either the Pka-C1k11302/Pka-C1k08918 or fuJ mutant phenotypes.
