Internal deletion, 5' breakpoint is just after Glu139 and the 3' breakpoint residing in the first intron. The result is an inframe mRNA transcript encoding an internally deleted protein.
Homozygous adults show no obvious mutant phenotype.
faxM34 Abl1/Df(3L)st-j7 individuals are lethal due to disruptions in the CNS longitudinal and commissural axons. One copy of Abl+mTnabl-lys moderately rescues and one copy of Abl+mTnabl completely rescues the lethality. faxM34 Abl1/Df(3L)st-g24 individuals are weakly viable, this semi-lethality can be alleviated by one copy of Abl+mTnabl.
"X ray" was stated as tentative. "ethyl methanesulfonate" was stated as tentative. Haploinsufficiency dependent upon an Abl mutant background (HDA).
