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.

Ett tillstånd som genotypiskt kännetecknas av mutation i den yttre änden av X-kromosomens långa arm (vid genpositionerna FRAXA eller FRAXE) och fenotypiskt av utvecklingsstörning, hyperaktivitet, krampanfall, språksvårigheter och förstorade öron, stort huvud (hög och bred panna) och förstorade testiklar.

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. Fragile X syndrome is characterized by developmental problems including intellectual disability and delayed speech and language development. Males are usually more severely affected than females. Fragile X syndrome (FXS) is a genetic condition that causes intellectual disability, behavioral and learning challenges, and various physical characteristics.

About a third of those affected have features of autism such as problems with social interactions and delayed speech. Through its intramural and extramural organizational units, the NICHD supports and conducts a broad range of research on Fragile X syndrome. Short descriptions of selected research studies are included below. NICHD researchers are also studying Fragile X-associated disorders, including Fragile X-associated primary ovarian insufficiency and Fragile X-associated tremor/ataxia syndrome. Fragile X syndrome is caused by a mutation in the FMR1 (fragile X mental retardation 1) gene on the X chromosome.

Fragile X syndrome (FXS) is a genetic disorder. FXS is caused by changes in a gene that scientists called the fragile X mental retardation 1 (FMR1) gene when it was first discovered. The FMR1 gene usually makes a protein called fragile X mental retardation protein (FMRP). FMRP is needed for normal brain development.
