RESEARCH QUESTION: Does a genetic condition underlie the diagnosis of primary ovarian insufficiency (POI) in a 13-year-old girl with primary amenorrhoea? DESIGN: A case report of a next-generation sequencing panel of 24 genes associated with syndromal and non-syndromal POI was conducted. RESULTS: A homozygous missense variant c.1076C>T, p.(Pro359Leu) in BMP15 was identified. CONCLUSIONS: The biallelic variant c.1076C >T, p.(Pro359Leu) in BMP15 is associated with primary ovarian failure.

RESEARCH QUESTION: Does a genetic condition underlie the diagnosis of primary ovarian insufficiency (POI) in a 21-year-old woman with primary amenorrhoea? DESIGN: A karyotype and genetic testing for Fragile X syndrome was undertaken. A next-generation sequencing panel of 24 genes associated with syndromal and non-syndromal 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.
