Imprecise excision of P{GawB}ADD1NP0793 resulting in deletion of 2R:7 ,857,967 - 2R:7 ,862,584 bp (FB2012_06 coordinates).
Deletion that eliminates most of the coding region of ADD1 without affecting the neighbouring gene.
A deletion resulting from the imprecise excision of P{GawB}ADD1NP0793 was mapped to release 5 genome coordinates 2R:7 ,857,967..7,862,584.
A dominant suppressor of variegation effect of ADD12 is observed in the In(1)wm4/Y background, which is stronger in homozygotes or ADD12/Df(2R)BSC153 trans-heterozygotes.
