Introduction: To the best of our knowledge, this is the first report of a comorbidity between Gilles de la Tourette's syndrome and 47 (XXX) syndrome. The clinical picture of Gilles de la Tourette's Syndrome is well described, while 47 (XXX) syndrome is much more rare and has a broader spectrum of possible phenotypic presentations.
Case Presentation: An Italian Caucasian girl was referred at the age of 11 to our Rehabilitation Center for anxiety and learning difficulties.
