Fragile X syndrome (FXS) is the most common form of hereditary mental retardation. FXS is an X-linked dominant genetic disorder with features that vary from person to person with FXS.
Difficulty adjusting to change
(From the National Fragile X Foundation Handbook for families and professionals)
Both males and females can be affected with FXS; however, because the gene is on the X-chromosome, more males are affected than females. As many as 1 in 4000 males and 1 in 8000 females have this syndrome. In the general population, approximately 1 in 300 women are carry the fragile X premutation, the form of the gene that can change to the full mutation when passed from mother to child. The full mutation can lead to FXS.
