Primary Ovarian Insufficiency_Premature Ovarian Failure
Gene: SPATA22
1 consanguineous family with two premature ovarian insufficiency (POI) and two nonobstructive azoospermia (NOA) patients. WES identified a homozygous variant in SPATA22 (c.400C>T:p.R134X). Histological analysis and spermatocyte spreading assay demonstrated that the spermatogenesis was arrested at a zygotene-like stage in the proband with NOA.
2nd patient found with idiopathic POI and compound heterozygous variants in SPATA22 (c.900+1G>A and c.31C>T:p.R11X).
