What are the chances of a person with this disease passing the disease to their offspring?

There is a great chance that the genetic mutation will be passed on, because it is a dominant mutation. In fact many children do contract this disease because it is prevalent in their family pedigree. In a popular reality T.V. show, on TLC, a family with dwarfism is recorded taking part in their day to day lives. The show called, Little People, Big World, is growing in popularity and is quite interesting. Both of the parents in the family have dwarfism, all though this disease is dominant, only one of the couples 4 children have dwarfism.
