What is the most common cause of fragile X syndrome?
What are the causes of fragile X syndrome? Fragile X is caused by
a mutation in the FMR1 gene
that prevents the body from making an important protein, called FMRP. This protein helps create and maintain connections between brain cells and the nervous system.
Is fragile X syndrome triggered by other factors?
Fragile X syndrome (FXS) is a genetic disorder. FXS is caused by
changes in a gene that scientists called FMR1 gene when it

What causes these issues in fragile X syndrome?
Nearly all cases of fragile X syndrome are caused by
a mutation in which a DNA segment, known as the CGG triplet repeat
