1. Introduction
Duchenne muscular dystrophy (DMD) is defined as a chronic form of dystrophy that is caused by a mutated gene. This essay critically discusses Duchenne muscular dystrophy as a whole, including all the symptoms, causes as well as treatment.

2. Overview of Duchenne muscular dystrophy
Duchenne muscular dystrophy was discovered by a French neurologist, Guillaume Duchenne. According to Emery (1994 : 23) Guillaume Duchenne invented an instrument, Duchenne’s trocar, to remove small portions of tissue in the body (biopsy).
Duchenne muscular dystrophy is a gender-linked inherited disorder. To illustrate, males only have one X chromosome, therefore they do not have a second X chromosome to make up for the damaged gene. Females can only become carriers of the disease, as females have a second X chromosomes to make up for the damaged gene.

According to Green (2014) the (DMD) gene for dystrophin, which is a protein that is present in muscles, is the second largest gene. A deficiency of dystrophin results in the damage of muscle fibres, resulting in a loss of muscle functioning. This disorder affects mainly the legs and pelvic region of the body. However it could also affect the heart, the respiratory system, as well as rarely the brain. Duchenne…
