Children born with DMD have a fault, known as a mutation, on their dystrophin gene. It can cause potentially life-threatening complications due to the weakening of the heart and muscles involved in breathing. Genetic Causes. Duchenne muscular dystrophy (DMD) is an inherited (genetic) condition which affects the muscles, causing muscle weakness. This causes errors in the instructions for making dystrophin, and the body is not able to produce a working dystrophin protein. However, it often occurs in people without a known family history of the condition. It is the most common muscular dystrophy, a kind of inherited muscle disease. A genetic disease is one that you are born with and you may have inherited from your family. In DMD, a variation or missing part of the dystrophin gene causes a loss of the dystrophin protein. It primarily affects males, but, in rare cases, can also affect females. Duchenne Muscular Dystrophy (DMD). There are different types of muscular dystrophy. Mutations in the DMD gene can cause a muscle-wasting disorder, called Duchenne muscular dystrophy, or its milder form, Becker muscular dystrophy.

Although the clinical and experimental investigations have made important advances in the treatment of symptoms, there is … This is a protein that plays a key role in protecting muscle fibers. For people with DMD, the fault on the gene means that they cannot produce … Inheriting muscular dystrophy. Simply put, defective genes cause MD. Duchenne muscular dystrophy, also called DMD, is a genetic disease affecting different groups of muscles in the body. It can be inherited in individuals with a family history of MD, or it can arise from a spontaneous mutation. Most are unable to walk by the age of 12. The disease is caused by a mutation on the X chromosome, particularly in the dystrophin, or DMD gene. What Causes Duchenne Muscular Dystrophy? It is the most common muscular dystrophy, a kind of inherited muscle disease. Duchenne Muscular Dystrophy Duchenne Muscular Dystrophy (DMD) is a genetic disease that causes muscle weakness and wasting. Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). DMD causes weakness and muscle loss that spreads throughout your child’s body. Introduction: Duchenne muscular dystrophy (DMD) is the most common inherited muscle disease in children. Weakness and loss of muscle mass cause serious difficulties in acquiring or maintaining walking, breathing and / or swallowing (Mayo Clinic, 2013). It mainly affects boys, and starts between ages 3 and 5. However, the illness is much rarer than Duchenne. It typically … Muscular Dystrophy Association. The mutation of this gene is found on the X chromosome, which means boys inherit the mutation from their mothers. You have two copies of every gene (with the exception of the sex chromosomes). DMD is one of four conditions known as … This protein loss prevents the muscle fibers from working properly, leading to weakness. However, very little was known about the causes of muscular dystrophy until the 1980s. This can result in trouble standing up. The main forms of muscular dystrophy may affect up to 1 in every 5,000 males.. DMD causes muscle cells to die, and results in the muscle becoming weak, small, and deformed. Becker muscular dystrophy is like Duchenne, except milder. Depending on the specific type of MD, the condition can be a: Duchenne muscular dystrophy is a form of muscular dystrophy.It worsens quickly. Duchenne muscular dystrophy … It mostly affects boys, though girls may be mildly affected.
