POI occurs when the ovaries stop working before age 40. Genetic causes account for approximately 10–28% of cases with FMR1 premutations a major identifiable cause.
How Genetic Is Premature Ovarian Insufficiency?
Genetics plays a meaningful role in Premature Ovarian Insufficiency, with heritability estimated at around 71%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Premature Ovarian Insufficiency: FMR1,BRCA1,BRCA2,MCM8. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Is Premature Ovarian Insufficiency hereditary, meaning it's passed directly from parent to child?
Premature Ovarian Insufficiency follows a multifactorial inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
