ABSTRACT
It is essential for educators to know about fragile X syndrome because this common disorder presents a variety of behavioural and cognitive problems, which continue from infancy throughout life. Fragile X has many consistent features, but each child has a different set of background genes that may be influenced in different ways. Some children may have mild learning difficulties, whereas others may have severe learning disabilities and autism. Some may have severe outbursts and aggression whereas others are easygoing.
