Expression of ptc^{Δloop2.Scer\UAS} under the control of Scer\GAL4^GMR16A06 does not result in a pruning defect in the mushroom body gamma neurons.

31% of embryos expressing ptc^{Δloop2.Scer\UAS} under the control of Scer\GAL4^nos.PG have five or more "lost" germ cells that have failed to coalesce with the somatic gonadal precursor cells (less than 5% of wild-type embryos have this many "lost" germ cells).

When clones are made expressing ptc^{Δloop2.Scer\UAS} (under the control of Scer\GAL4^αTub84B.PC) in adult abdominal segments all clone cells that have anterior provenance, form pigmented (segmental region anterior 3 (a3)) cuticle. The polarity is largely reversed, even at the back of the clone and in some places behind it.

Expression of ptc^{Δloop2.Scer\UAS} under the control of Scer\GAL4¹⁴⁰⁷ results in a decrease in the size of the brain in embryos. The frontal commissure is present.

Somatic clones of ptc^{Δloop2.Scer\UAS.cBa} cells in the wings of Scer\GAL4^Bx-MS1096 animals only cause a visible phenotype when they are located in the posterior portion of the anterior (A) compartment, next to the anterior/posterior (P) boundary. Such clones are associated with the formation of mirror-symmetric anterior winglets in place of the normal A compartment and with a dramatic reduction in the P compartment. The anterior border of such clones coincides with the plane of symmetry of the anterior winglet. In larvae, clones of cells expressing ptc^{Δloop2.Scer\UAS.cBa} under the control of Scer\GAL4^αTub84B.PP in the posterior of the anterior compartment of wing discs have a smooth, straight anterior border.
