Abstract
It is thought that learning disability due to the fragile X syndrome occurs in approximately one in every 2000 to 3000 male births. This is a very high figure, so this cause of learning disability in boys is thought to be one of the most common. Girls are also affected, but to a lesser degree due to the mode of inheritance. Only 30% to 40% of girls carrying this genetic abnormality will have some degree of learning disability.
