The 3' end of the Zzzz\CGG repeat array has been contracted, leaving 60 copies, with repeat fragment consisting of the sequence (CGG)[[9]]AGG(CGG)[[9]]AGG(CGG)[[40]].
Scer\GAL4elav-C155-driven expression of Zzzz\CGG60.Scer\UAS.T:Avic\GFP-EGFP has no adverse effect on viability.
Strong expression of Zzzz\CGG60.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4GMR.PF results in rough eyes, loss of pigmentation, and holes are seen in tangential sections of the eye. Moderate expression has no effect on the eye.
Strong expression of Zzzz\CGG60.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4elav-C155 results in reduced viability, while moderate expression has no effect.
Strong expression of Zzzz\CGG60.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4Act5C.PI results in late larval lethality, while moderate expression has no effect.
Rm62[+]/Rm6201086, Scer\GAL4elav-C155, Zzzz\CGG60.UAS.EGFP has partially lethal - majority live phenotype
Scer\GAL4elav-C155, Zzzz\CGG60.UAS.EGFP, sbr12/sbr[+] has partially lethal - majority die phenotype
Rm6201086 or sbr12 heterozygotes expressing Zzzz\CGG60.Scer\UAS.T:Avic\GFP-EGFP driven by Scer\GAL4elav-C155 display reduced viability compared to controls. None of these manipulations alone causes any viability deficits.
