Understand Duchenne Duchenne Muscular Dystrophy Duchenne muscular dystrophy (DMD) is the most common fatal genetic disease diagnosed in childhood. The disease almost always affect boys, and they tend to be diagnosed before the age of 5. Duchenne muscular dystrophy is classified as a rare disease. There are around 2,500 patients in the UK and an estimated 300,000 sufferers worldwide. Children born with Duchenne muscular dystrophy have a fault, known as a mutation, on their dystrophin gene, the longest gene in the body. The fault means that they cannot produce dystrophin, a protein that is vital for muscle strength and function. This lack of dystrophin results in a progressive deterioration of muscle strength and function. You can read more about the disease in our Duchenne In Detail section. Diagnosing Duchenne The first noticeable symptom of Duchenne may be a delay in the motor milestones of a young child. These milestones include sitting and standing independently. Further tests are then needed to diagnose Duchenne, starting with a blood test and then followed by either genetic tests or a muscle biopsy. Read here for more information on diagnosing Duchenne. Newly Diagnosed Diagnosis can be a time of overwhelming shock and despair. Feelings of anger, fear, helplessness, guilt and loneliness can be overwhelming.

We have divided up the stages of Duchenne muscular dystrophy here. Current Drugs & Supporting Therapies There are currently very few drugs that are prescribed for Duchenne. We have summarised these here. There are some supporting therapies that are recommended to help manage the symptoms of Duchenne, and you can read more about those here. Treatments In The Pipeline There are many drugs now in development to treat the underlying cause and the various symptoms of Duchenne muscular dystrophy. The landscape has changed beyond recognition in recent years. Some drugs are now being tested on patients with Duchenne muscular dystrophy and many others are about to start clinical trials.
