The number of individuals in the U.S. who have or are at risk for a premutation-associated condition ranges from 1 in 151 females, or about 1 million women, to 1 in 468 males, or about 350,000 men.; Among premutation carriers, about 40% of males older than 50 years and 8%–16% of women older than 40 years develop FXTAS.; …
FXTAS only occurs in individuals who have a Fragile X (FMR1) premutation. Therefore, it is essential that anyone being considered for this diagnosis is testedfor and confirmed as a premutation carrier. This involves DNA testing of the individual’s FMR1 (Fragile X) gene.
