<unk>  is an autosomal dominant disorder, where one copy of the relevant mutation is enough to cause the condition. Most cases are de novo, or spontaneous mutations that do not occur in the proband's parents; approximately 75% are de novo, while 25% are inherited. People with<unk>  microdeletions who have normal fertility have a 50% chance of passing the deletion down to their offspring. Environmental factors have not been implicated in the syndrome.
