Duchenne muscular dystrophy is a life-shortening muscle-wasting condition, caused by the lack of a vital muscle protein called dystrophin. The condition causes muscles to weaken and waste over time, leading to increasing and severe disability.
Duchenne muscular dystrophy currently affects around 2,500 people in the UK and around 100 babies are born with the condition each year.
It is caused by genetic mutations on the ‘X’ chromosome, meaning almost all of those affected are male. These mutations prevent the body from producing the vital protein, dystrophin, needed to build and repair muscle.
