A mutation that moves the gene next to a new regulatory element (such as a promoter or enhancer) can result in spontaneous ectopic gene expression, as the new regulatory element may turn on the gene inappropriately. Insertion and deletion mutations can also potentially result in ectopic gene expression, but they are less common causes.
