Fragile X syndrome
It is usually caused by an X chromosome that carries a mutation of a particular gene. It is a genetic defect and may be inherited. Fragile X is twice as common in boys as in girls and its effects are milder in girls. It is thought that this is because girls have two X chromosomes and that one can perhaps compensate for the other. Fragile X affects behaviour, emotions,[link widoczny dla zalogowanych], learning, speech and language. The range of effects is great and it is not possible to predict which of the many potential difficulties a child with fragile X will have. Indeed, it is possible for a child to have the damaged gene and yet not be affected by it at all. Children with fragile X often have high verbal abilities and have a good sense of humour. It is important however to ensure that the child with fragile X is not subjected to too many environmental stimuli (eg. sounds,[link widoczny dla zalogowanych], movements, smells) at once. Children with fragile X are sometimes given medication to improve their concentration.Key characteristicsA child with fragile X syndrome may: repeat words and phrases, or the last words in a sentence, over and over fail to respond to direct questions give answers not obviously related to the question speak in rapid bursts have poor fine and gross motor coordination dislike work based on writing find large, noisy, unstructured group times distressing find it easier to learn in the morning, after a settling-in period become distressed by eye contact, touch, questioning in front of others react badly to pressures of time be oversensitive to relatively minor upsets and/or have disruptive outbursts prefer practical, physical activities have slight motor coordination problems enjoy repetitive tasks, which may have a calming effect have subtle physical characteristics, such as a large head, long face, large jaw, protruding ears, high palate or dental overcrowding. Support strategiesYou may need to: provide as much positive attention as possible have an organised set of routines and make sure that the child is notified of any changes in these routines well in advance set up an agreed reward system for good behaviour, rather than using too many sanctions for inappropriate behaviour reward specific behaviours and explain this clearly praise every small achievement make use of visual clues give short, simple instructions – for complex tasks, give only one or two instructions at a time be consistent in the use of rules and routines let children work in an individual or paired situation,[link widoczny dla zalogowanych], rather than expecting them to work in groups be realistic in your expectations, setting short, clearly defined targets.

The exclusionThe head teacher wrote to the parents of R and F telling them that neither R nor F could come back to school, but that they would be given help in completing their course at home. He should, of course, have told the parents immediately, ideally by telephone followed by a letter, of their right to make representations to the governing body.
