From the paper:

"Fragile X is the most common inherited cause of developmental and learning disabilities, affecting as many as one person in every 1,000 (Saunders, 1999). Fragile X is a sex-linked genetic disorder and is named so because of a fragile site on the tip of the long arm of the X chromosome where it looks as if a piece of the chromosome is broken off (Saunders, 1999). The gene responsible for the disorder is Fragile Mental Retardation 1 (FMR-1) and can be diagnosed through DNA testing (Saunders, 1999). The FMR-1 gene becomes faulty due to an expansion of three nucleotides, Cytosine-Guanine-Guanine (CGG), which inhibits the production of the FMR protein; the FMR protein is essential for normal brain development (Symons, et al, 2001).
