Several factors can affect a woman's risk for POI:
- Family history. Women who have a mother or sister with POI are more likely to have the disorder.3
- Genes. Some changes to genes and genetic conditions put women at higher risk for POI. Research suggests that these disorders and conditions cause as much as 28% of POI cases.3 For example:
- Women who carry a variation of the gene for Fragile X syndrome are at higher risk for Fragile X-Associated POI (FXPOI).4 Fragile X syndrome is the most common inherited form of intellectual and developmental disability, but women with FXPOI do not have Fragile X syndrome itself. Instead, they have a change or mutation in the same gene that causes Fragile X syndrome, and this change is linked to FXPOI. Visit the What is the connection between POI and Fragile X syndrome? section of the site for more information.
- Most women who have Turner syndrome develop POI. Turner syndrome is a condition in which a girl or woman is partially or completely missing an X chromosome. Most women are XX, meaning they have two X chromosomes. Women with Turner syndrome are X0, meaning one of the X chromosomes is missing.
- Other factors. Autoimmune diseases, viral infections, chemotherapy, and other treatments also may put a woman at higher risk of POI.2
