What is Fragile X Syndrome (FXS)? | CDC Fragile X syndrome (FXS) is a genetic disorder. A genetic disorder means that there are changes to the person’s genes. FXS is caused by changes in the fragile X mental retardation 1 (FMR1) gene. The FMR1 gene usually makes a protein called fragile X mental retardation protein (FMRP). FMRP is needed for normal brain development. What is Fragile X Syndrome (FXS)? | CDC

May 25, 2016 · Fragile X syndrome (FXS) is one of the more common known causes of intellectual disability that can run in families (inherited). FXS is caused by a change in the genetic material in each cell of the body.

Fragile X syndrome is the name given to this condition because some affected individuals have an X chromosome that looked as if it had “broken” or was “fragile” and was held together by the slightest of ties. This technique is no longer used in the diagnosis of this syndrome because it is both less accurate and costlier than are
