Fragile X syndrome (FXS) is the most common inherited cause of autism and intellectual disabilities. It affects 1 in 4,000 boys and 1 in 8,000 girls worldwide. Fragile X syndrome occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development.

It affects about 1 in 4,000 males and 1 in 8,000 females and occurs in all racial and ethnic groups. Fragile X syndrome occurs in individuals with an FMR1 full mutation or other loss-of-function variant and is nearly always characterized in affected males by developmental delay and intellectual disability along with a variety of behavioral issues.

Fragile X syndrome (FXS) occurs due to a loss of function mutation in the fragile X mental retardation 1 (FMR1) gene on the X chromosome. FMR1 codes for fragile X mental retardation protein (FMRP), which is important in brain and gonadal (testes and ovaries) development.

Personer med FXS har vanligvis flere fellestrekk i utseende, symptomer og atferd, men det er store variasjoner i omfang og grad av vanskeligheter. Fragile X syndrome (FXS) is an inherited genetic disease passed down from parents to children that causes intellectual and developmental disabilities. It’s also known as Martin-Bell syndrome. Fragile X syndrome is caused by a mutation in the FMR1 (fragile X mental retardation 1) gene on the X chromosome. The FMR1 gene codes for the fragile X mental retardation protein, which plays a role in cognitive development in the brain. It is X-linked, but it is unclear whether it is dominant or recessive.
