Fragile-X Syndrome of Mental Retardation Charles D. Laird Departments of Zoology and Genetics, University of Washington NJ-15, Seattle, Washington 98195 Manuscript received July 10, 1987 Accepted July 3 1, 1987 ABSTRACT A mechanism is proposed for the inheritance and expression of the fragile-X-linked syndrome of mental retardation in humans.

Fragile X is the most common cause of inherited intellectual disability, which affects approximately 1 in 4,000 males and 1 in 8,000 females. 1 Carrier screening for Fragile X will detect approximately 99% of individuals who are carriers of a mutation in the Fragile X gene and at risk of having a child with Fragile X syndrome. 2

However, we all don’t talk genetics every day, so it can be a hard concept to follow. In fact – surprisingly – we still hear of doctors incorrectly stating how the gene mutation is passed down. Fragile X syndrome (FXS) is inherited in an X-linked dominant manner. A condition is X-linked if the responsible gene is located on the X chromosome . The inheritance is dominant if having only one changed ( mutated ) copy of the responsible gene is enough to cause symptoms of the condition. Fragile X syndrome is inherited in an X-linked dominant pattern.

Fragile X syndrome affects around 1 in 3,600 boys and between 1 in 4,000 – 6,000 girls. Apr 9, 2008 Fragile X syndrome is inherited from individuals, usually females, who typically carry an unstable premutation allele of the CGG-repeat tract in Jul 1, 2005 Fragile X syndrome is caused by an expansion mutation in the Fragile X mental retardation 1 (FMR1) gene located on the X chromosome It Fragile X syndrome is an X-linked recessive disease associated with expansion of a trinucleotide repeat (CGC) within the FM1 gene. This mutation results in the Fragile X syndrome is an inherited disorder associated with mental retardation and a particular appearance. It is caused by an error in a small piece of the… Fragile X syndrome (FXS) is the leading known inherited cause of intellectual disability and autism spectrum disorders (ASDs).

In some people with this condition, cognitive function is described as borderline, which means that it is below average but not low enough to be classified as an intellectual disability. Doctor Gul Dolen explains that Fragile X syndrome is not a mendelian disorder, because the inheritance pattern in slightly different. Fragile X syndrome is the most common form of inherited mental retardation. The disorder is mainly caused by the expansion of the trinucleotide sequence CGG located in the 5' UTR of the FMR1 gene on the X chromosome.

signs and symptoms of Fragile X syndrome. Males and females with 55 to 200 repeats of the CGG segment are said to have an FMR1 gene pre-mutation.

A father with the altered gene for Fragile X on his X chromosome will pass that gene on only to his daughters. Fragile X is caused by a mutation in a single gene, called the FMR1 gene. This gene is on the X-chromosome, which is one of two possible sex chromosomes, the other being Y. Being on the X chromosome makes Fragile X Syndrome an X-linked dominant inheritance pattern. As mentioned above, fragile X syndrome is caused by a mutation in the FMR1 gene located on the X chromosome at Xq27.3. Individuals with fragile X syndrome nearly always have (in greater than 99% of cases) a full mutation of the FMR1 gene which means that they have over 200 CGG repeats and abnormal methylation of the gene.

The inheritance is much more complex compared to many other genetic diseases.
