Research Question. Does a genetic condition underlie the diagnosis of primary ovarian insufficiency (POI) in a 21 year old woman with primary amenorrhea. Design. A karyotype and genetic testing for Fragile X syndrome was undertaken. A next gen-eration sequencing panel of 24 genes associated with syndromal and nonsyndromal POI was conducted. Results. A nonsense variant c.1336G>T, p.(Glu446Ter) and whole gene deletion in STAG3 were identified. Conclusions. Biallelic loss of function variants in STAG3 are associated with primary ovarian failure type 8 and are a rare cause of POI.
