Duchenne Muscular Dystrophy
Inheritance patterns and prenatal diagnosis
Inheritance patterns
DMD is a genetic condition inherited as an X-linked trait. Often there
are no other members of the family affected. This is usually the result
of a de-novo genetic event that has occurred in the affected child; or
the fact that the mother, if she is a carrier of the genetic defect,
usually does not manifest any sign of the disease (because of the
X-linked inheritance). The gene responsible for DMD is known and
mutations can be relatively easily found in approximately two thirds of
affected children.
Prenatal diagnosis
This and carrier detection is available through Clinical Genetic Centres.
