Two lesions in the wg promoter; a 17bp deletion from -375 to -359, and a 6bp alteration from -336 to -331 (CGC to ACC change plus 3bp deletion) relative to the transcription start site.
Deletion of 6 bases (-336 to -331) and insertion of three (ACC) in the wg at the same location in the wg promoter. One of two mutations in the wg promoter in wgDeltaC1.
