Cis -regulatory mutations cause an allele-specific change in the focal gene's expression and tend to be located close to the focal gene.

Trans-acting factors can be categorized by their interactions with the regulated genes, cis-acting elements of the genes, or the gene products. DNA binding trans-acting factors regulate gene expression by interfering with the gene itself or cis-acting elements of the gene, which lead to changes in transcription activities. This can be direct initiation of transcription, promotion, …
