Description

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.

Additional Comments
Genetic Interactions
Statement
Reference

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.
