Fragile X syndrome, also known as Martin-Bell syndrome, is a genetic
disorder caused by an anomalous chromosome. It is secondary to damage to the end part of the sexual chromosome X. Fragile X syndrome induces mental retardation in boys, carriers of one x chromosome, along with physiological abnormalities. They notably present with large, protruding ears, an elongated face, or even testicular hypertrophy
. Women are generally less affected than men, and if they are the disorder is less pronounced, with mental retardation incidence at only 50%. There currently exists no cure for this syndrome, and treatment consists essentially of educating and socializing.
