How can a gene be longer than an mRNA produced by that gene?…

Questions

Hоw cаn а gene be lоnger thаn an mRNA prоduced by that gene? For instance, the gene for Duchenne muscular dystrophy (DMD) is over 2000 kb (kb = kilobases) long, but the mRNA that this gene produces and that is found in polyribosomes is approximately 14 kb long. What causes this discrepancy?
