Physical characteristics of young boys with fragile X syndrome: reasons for difficulties in making a diagnosis in young males. Am J Med Genet 2000; 92: 229-236. Lewis P, Abbeduto L, Murphy M, Richmond E, Giles N, Bruno L et al. Cognitive, language and social-cognitive skills of individuals with fragile X syndrome with and without autism. Fragile X syndrome is caused due to mutation of a single known present on the X chromosome and known as Fragile X Mental Retardation 1 or FMR1.

A DNA test is available and is 99 percent accurate for the syndrome. There is no cure for Fragile X syndrome. Treatment of Fragile X syndrome consists largely of treating the symptoms. Males with the full mutation have fragile X syndrome. The fragile X chromosome is subject to random X inactivation.

CDC is working to learn more about fragile X syndrome and fragile X-associated disorders to improve the health and well-being of people with these conditions.

“The school put a lot of pressure on John and David—thinking their challenges were a result of bad behavior—instead of managing the environment so they didn’t get anxious and upset. The Fragile X premutation can be passed silently down through generations in a family before a child is born with the syndrome.

Fragile X syndrome (FXS) is a genetic disorder characterized by mild-to-moderate intellectual disability. The average IQ in males is under 55, while about two thirds of affected females are intellectually disabled. Ruth and Earl raised their sons before there was a diagnosis of fragile X syndrome. “The school put a lot of pressure on John and David—thinking their challenges were a result of bad behavior—instead of managing the environment so they didn’t get anxious and upset. The Fragile X premutation can be passed silently down through generations in a family before a child is born with the syndrome. Women who carry Fragile X have a 50% chance of passing the mutated gene to each of her children. If she passes the affected gene, her children will either be carriers or they will have Fragile X syndrome.

The Fragile X gene is only carried on an X chromosome; both males and females may transmit a Fragile X (FMR1) gene on their X chromosome so either a man or a woman may be a carrier. The signs and symptoms of Fragile X syndrome have five general categories where individuals often show altered or arrested development. I'm a carrier of the Fragile X (FX) gene and a single mother of two adult daughters: my eldest (now 22 yrs. old,) was born without my affected X chromosome and is a very intelligent and dynamic young woman, while my youngest (now 21 yrs.,) was born with my affected X, and at age 12 was accurately diagnosed as having "Fragile X Syndrome with autistic tendencies." A boy with fragile X syndrome. Note the prominent and elongated ears and long face. Children from different ethnic groups have similar characteristics.

The fragile X syndrome (FXS) is one of the most common forms of hereditary intellectual disability (Glover Lopez, 2006). At the genetic level, it is a pathology linked to the X chromosome, which is why it is more frequently affected by the male sex.

T … Fragile X syndrome (FXS) is the most common inherited form of mental impairment and autism, and one of many types of intellectual dysfunction associated with gene defects in the X chromosome. The first clinical description of FXS by Martin and Bell dates back to 1943, while its association with a fragile site on the X chromosome was established in 1969. Fragile X syndrome (FXS) is one of the most common causes of inherited intellectual disability. CDC is working to learn more about fragile X syndrome and fragile X-associated disorders to improve the health and well-being of people with these conditions.
