People with Duchenne’s muscular dystrophy doesn’t make dystrophin due to the mutations in the gene producing dystrophin.
Step-by-step explanation:
Duchenne's muscular dystrophy is an X linked genetic disorder and in people with DMD over there is little production of muscular dystrophy. The chance of males having DMD is more than females having this disorder.
If a boy inherits the affected X chromosome from his mother, then he will be a DMD patient, since males have only one X chromosome.
The protein dystrophin is necessary to help muscles maintain their structure. When the gene responsible for the production of dystrophin is had mutations which cause Duchenne’s muscular dystrophy.
