Is Duchenne Muscular Distrophy Non disjunction?

Duchenne Muscular Dystrophy (DMD) is not typically caused by non-disjunction. It is primarily caused by mutations in the dystrophin gene on the X chromosome, often due to deletions or duplications of genetic material rather than errors in chromosome separation during cell division. Non-disjunction can lead to chromosomal abnormalities, such as Turner syndrome or Down syndrome, but DMD is specifically linked to genetic mutations rather than chromosomal number changes.
