Large deletion in the open reading frame.
Deletion of 2.1kb detected by Southern blot at coordinate +75kb of the genomic DNA walk.
The addition of msl-1γ269 to flies containing a single copy of msl-1Δ84.T:Zzzz\FLAG in weak heatshock conditions has no effect on the male viability phenotype seen in these flies. The addition of msl-1γ269 to flies containing a single copy of msl-1C.hs.T:Zzzz\FLAG in weak heatshock conditions has no effect on the male viability phenotype seen in these flies.
72% of msl-1γ269/+ females carrying msl-1Hsp83.PC are viable. msl-1γ269/+ females carrying both msl-1Hsp83.PC and msl-2Hsp83.PK survive to the third larval instar stage.

Expression of msl-1Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4αTub84B.PL at 25[o]C completely rescues the male-specific lethality of msl-1L60/msl-1γ269 flies.
Expression of either msl-1mut1.Scer\UAS.T:Zzzz\FLAG, msl-1mut3.Scer\UAS.T:Zzzz\FLAG, msl-1mut4.Scer\UAS.T:Zzzz\FLAG or msl-1mut5.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4αTub84B.PL at 25[o]C fails to rescue the male-specific lethality of msl-1L60/msl-1γ269 flies.
H4Ac16, acetylated form of His4, is not localised to the X chromosome in male salivary gland nuclei of msl-1γ216/msl-1γ269 heterozygotes.
