Eileen Furlong, Oliver Stegle and colleagues quantify transcriptional start site (TSS) usage across 81 Drosophila lines, identifying genetic variants that affect transcript levels or the distribution of the TSS within a promoter. Using single-cell measurements, they show that variants modulating promoter shape often increase expression noise.
