It is the most common form of inherited intellectual disability in males and a significant cause of intellectual disability in females. Fragile X syndrome is a genetic disorder which occurs as a result of a mutation of the fragile X mental retardation 1 (FMR1) gene on the X chromosome, most commonly an increase in the number of CGG trinucleotide repeats in the 5' untranslated region of FMR1.

2021-04-07 Fragile X syndrome is a genetic disorder that occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should. Fragile X-associated Disorders are a family of inherited conditions caused by alterations (expansions) in the FMR1 gene (Fragile X gene) which is located on the X chromosome. These disorders include a wide range of physical, intellectual and behavioural symptoms that … An X-chromosome with a fragile site near the end of the long arm, resulting in the appearance of an almost detached fragment.

At the start of this gene lies a region of DNA which varies in length from one person to another. Ordinarily, this stretch of DNA falls within a range of length that would be considered “normal”. 1.
