What is a Carrier?

A carrier of Duchenne Muscular Dystrophy is a female who has a genetic mutation in the DMD gene that would prevent the production of dystrophin on one of her X chromosomes.

Women who suspect they might be a carrier may want to consider talking to a doctor about genetic testing. Genetic testing is used to identify genetic mutations and can determine whether the person being tested carries a genetic mutation that could be passed on to their children.

You can also ask your Paediatric Neurologist for a referral letter to test through Ampath / Lancet


Carriers have a significant risk of passing an existing genetic mutation to their sons, who would be affected, or to their daughters, who could be carriers. The inheritance pattern is when a carrier mother has a son, there is a 50% chance he will be affected with Duchenne. If she has a female, there is a 50% chance her daughter will be a carrier.
