Classic features of FXS are elongated face, large and protruding ears, and macroorchidism. Other physical features and medical problems may include high-arched palate, strabismus, refractive error, frequent sinusitis and otitis, excessive joint laxity, hyperextensible metacarpophalangeal joints, double-jointed thumbs, flat or pronated feet, softness and smoothness of the skin, hand calluses, cardiovascular abnormalities (e.g., aortic root dilation, mitral valve prolapse), neurological involvement (e.g., hypotonia, motor incoordination, and seizure), gastrointestinal problems (e.g., gastroesophageal reflux, constipation, and loose bowel movements), obstructive sleep apneas, and unusual growth patterns (e.g., increased birth weight, macrocephaly).
At physical examination bilateral nystagmus, microcephaly, spastic quadriplegia, and macroorchidism were noted.
McCune Albright syndrome may lead to pituitary micro or macroadenomas and related excessive secretion of GH and/or prolactin, acromegaly due to severe FD, unilateral or bilateral macroorchidism and rarely a clinical picture of precocious puberty secondary to sulphatase activity.

An estimated one in 3,800 males exhibits the full mutation, and about 90 percent of those with the full mutation will display low IQ, characteristic physical features such as an elongated face and macroorchidism (grossly enlarged testes), and behaviors such as hand-flapping and palm-biting.
