Fragile X syndrome is one of the most common forms of inherited intellectual disability, affecting 1 in 5,000 males 1. The vast majority of cases are caused by the expansion of a CGG-trinucleotide repeat in the 5′ untranslated region of the X-linked FMR1 gene 2.

Individuals with fragile X syndrome can also have extreme anxiety, sensory disorders, social withdrawal, aberrant behavior, aggressive behavior, and stereotypic (repetitive and without function) behaviors like hand-flapping and body rocking. Many of these behaviors, including gaze avoidance, can cause fragile X syndrome to be mistaken for autism.

What causes Fragile X Syndrome. When the gene lengthens it switches off production of a protein that is involved in brain development and other functions. Females have two X chromosomes and males have one X and one Y.
