Both types of myotonic dystrophy are inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with the condition.
Can anyone be a candidate for myotonic dystrophy?
Men and women are equally likely to pass on Myotonic Dystrophy to their children. Myotonic Dystrophy is a genetic disease and so can be inherited by the child of an affected parent if they receive the mutation in the DNA from the parent. The disease can be passed on and inherited equally by both sexes.
Who is at risk for myotonic dystrophy?
If a person has between 38-49 CTG repeats, they will usually not develop symptoms, but their children will be at risk of developing myotonic dystrophy. In general, the more repeats there are, the more severe the symptoms will be.
