Ovarian Insufficiency(FXPOI) What is FXPOI? FXPOI is a condition caused by a premutation (55-200 CGG repeats) in the FMR1 gene. As a result, females experience irregular or cessation of menses before age 40. Females with a premutation have a 20% (1/5) risk of FXPOI, with the highest risk of FXPOI being 80-100 repeats.
