What causes Duchenne muscular dystrophy?

Duchenne muscular dystrophy is caused by a defective gene. The mutation of this gene is found on the X chromosome, which means boys inherit the mutation from their mothers. The particular genetic mutation that causes Duchenne muscular dystrophy causes a lack of a muscle protein called dystrophin. This leads to symptoms like muscle weakness and difficulty with walking or running, which are usually apparent in very early childhood.
