WebFragile X syndrome is caused by the expansion or lengthening of the FMR1 gene on the X chromosome, known as a gene mutation. The X chromosome is one of two sex-determining chromosomes. When the gene lengthens it switches off the production of a protein that is involved in brain development and other functions.
