This page is under development.
Fragile X (FX) is a family of conditions, including Fragile X Syndrome (FXS) and Fragile X Premutation Associated Conditions (FXPAC).
Fragile X Syndrome (FXS) is an inherited condition whereby the FMR1 gene is switched off, or partially switched off, in X chromosomes. Those with FXS have the ‘full mutation’, whereby those who are carriers have the ‘premutation’.
Fragile X Premutation Associated Conditions (FXPAC) includes Fragile X-associated Tremor/Ataxia Syndrome (FXTAS), Fragile X Primary Ovarian Insufficiency (FXPOI) and other conditions associated with the Fragile X Premutation.
There is information in English on Fragile X conditions via our colleagues in the U.K. fragilex.org.uk
