Homozygous adults have a cleft in the fan-shaped body and a ventrally opened ellipsoid body with intermediate penetrance. sccP/Df(3L)emc-E12 flies have no mutant adult central brain phenotype. Heterozygotes have no adult central brain defect.
sccP is a suppressor of mushroom body phenotype of Ptpmeg1
sccP is a suppressor of ellipsoid body phenotype of Ptpmeg1
Excision of the P{GawB} element can revert the mutant phenotype.
