Fragile X Syndrome
(from the National Library of Medicine)

A genetic condition caused by spontaneous breaks in the long arm of the X chromosome.

Fragility of the long arm of the X chromosome is thought to be a result of increased methylation at the site of the break. The Fragile X accounts for approximately one-third of all X-linked mental retardation in males and one-tenth of that in females. This syndrome occurs in approximately 1 out of 2,000 males and 1 out of 1,000 females.

Genetic counseling may be of benefit for prospective parents with a family history of Fragile X syndrome.

Symptoms

• family history of fragile X syndrome
• mental retardation
• large ears
• oversized testes in the male
