ABSTRACT
It is now widely acknowledged that a diagnosis, wherever possible, is of utmost importance to individuals who have developmental difficulties, for genetic reasons as well as to their families and carers. Indeed, diagnoses can take many forms, and this is a common cause of confusion for those who work with children and young people who have fragile X syndrome. An individual may have multiple diagnoses, all of which are important for different reasons, and all of which may have implications for intervention and support.
