Alternative Promoters for the Human Dystrophin gene

The human dystrophin gene extends almost 2.5 million bases, and includes a large number of exons separated by larger intron regions. Depending on the tissue type and developmental stage, any of seven different promoters (start signals) may be used to transcribe all or a part of the gene region and produce variants of the gene product.
