Suppresses position effect variegation (PEV) at the w locus caused by In(1)wm4, PEV at the B locus caused by Dp(1;Y)BarSCV, PEV at the Sb locus caused by T(2;3)SbV and PEV at the bw locus caused by In(2R)bwVDe2.
Suppressor of In(1)wm4h position-effect variegation.
Homozygous follicle cell clones show epithelial defects, including stacking of follicle cells.
Heterozygosity for Df(2R)en-A results in 0.9% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.
Shows no maternal enhancement of dpphr4.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Deficient embryos show an uninterpretable mutant midgut phenotype.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Defective in gonad assembly.

The stock contains a second-site deletion uncovering l(2)gl.
The Df(2R)en-A chromosome may act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion), but the eye colour phenotype in the presence of Df(2R)en-A overlaps the eye colour phenotype in a wild-type background so it cannot be unequivocally demonstrated that the deficiency chromosome uncovers a suppressor of telomeric silencing.
The left Df(2R)en-A breakpoint lies within CG13230 or shn or in the region between them, and lies in the range 2R:7042690..7102254 (R5) (predicted cytology: 47D5-47D7).
The right Df(2R)en-A breakpoint lies within CG9005 or CG9003 or in the region between them, and lies in the range 2R:7509389..7531762 (R5) (predicted cytology: 48A3-48B2).
