Internal deletion, 5' breakpoint is 277 nucleotides within the first intron and the 3' breakpoint is 239 nucleotides in exon 2 at Leu335. The result is an inframe mRNA transcript encoding an internally deleted protein.
Homozygous adults show no obvious mutant phenotype.
faxM7/fax[+] is an enhancer of visible | adult stage phenotype of Hsap\ABL1::Hsap\BCRUAS.cBa, Scer\GAL4GMR.PU
faxM7/fax[+] is an enhancer of lethal | prepupal stage phenotype of Abl4/Abl1
faxM7/fax[+] is an enhancer of lethal phenotype of trioM89/trioS036810
faxM7/fax[+] is an enhancer of eye phenotype of Hsap\ABL1::Hsap\BCRUAS.cBa, Scer\GAL4GMR.PU
faxM7 Abl1/Df(3L)st-j7 individuals are lethal due to disruptions in the CNS longitudinal and commissural axons. One copy of Abl+mTnabl-lys or Abl+mTnabl moderately rescues the lethality. faxM7 Abl1/In(3L)std11 individuals are also lethal, one copy of Abl+mTnabl rescues and Abl+mTnabl-lys fails to rescue the lethality. The presence of NrtM2 does not affect lethality. faxM7 Abl1/Df(3L)st-g24 individuals are weakly viable, this semi-lethality can be alleviated by one copy of Abl+mTnabl. Dosage sensitive interactions exist between faxM7 and NrtM2. Abl+mTnabl is unable to rescue the lethality of fax- Nrt- individuals.
"X ray" was stated as tentative. "ethyl methanesulfonate" was stated as tentative. Haploinsufficiency dependent upon an Abl mutant background (HDA).
