The landscape of Duchenne is changing, with new disease management strategies available and under development. Many of these are based on specific genetic mutations. Knowing your child's mutation can affect decisions on which strategies might be appropriate for your child. Learn more about genetic mutations in Duchenne.
The dystrophin gene is the largest gene in the body, made up of exons (sections of genes) that are linked together to form the instructions for making dystrophin — a protein muscles need to work properly. One of the most common mutations in people with Duchenne is an exon deletion, when one or more exons are missing.
