What are Fragile X-Associated Disorders?

Fragile X-associated disorders (FXD) is a family of genetic conditions that can affect individuals in a variety of ways. The conditions are all caused by changes in the gene known as FMR1. Fragile X syndrome (FXS) is caused by a full mutation of the FMR1 gene. Fragile X-associated tremor/ataxia syndrome (FXTAS) and Fragile X-associated primary ovarian insufficiency (FXPOI) are caused by a premutation of the FMR1 gene.
