چکیده
Abstract Study question Are the gene variants involved in meiosis initiation responsible for premature ovarian insufficiency (POI)? Summary answer MEIOSIN variant participates pathogenesis of human POI by impairing due to insufficient transcriptional activation essential meiotic genes. What is known already Meiosis key event establishment reserve, and several defects homologous recombination have been found contribute POI. However, genes not associated with design, size, duration Retrospective genetic study. An in-house whole exome sequencing (WES) database 1,030 idiopathic patients was screened variations Participants/materials, setting, methods Gene were WES cases. The pathogenicity variation verified vitro experiments, including protein structure prediction dual-luciferase reporter assay. effect on function demonstrated through histological analyses a point mutation mouse model. Main results role chance A homozygous that initiates via retinoic acid dependent pathway identified patient assay revealed adversely affected upregulating Further knock-in mice confirmed impacted prophase I program accelerated oocyte depletion. Limitations, reasons caution studies are needed explore other Wider implications findings present study firstly pathogenic Although causative rare POI, our expanded spectrum elucidated different mechanisms infertility.

Role of microRNAs in premature ovarian insufficiency
Premature ovarian insufficiency (POI) is a typical disorder of amenorrhea lasting for a minimum of 4 months. The typical characteristics comprised of declined estrogen and raised serum concentrations of follicle-stimulating hormone (FSH) in women <40-year-old, primarily originating from iatrogenic factors, karyotypic abnormalities, and genetic factors. However, the etiology of POI remains unkno...

BACKGROUND To evaluate the involvement of immune abnormality in patients with idiopathic premature ovarian insufficiency (POI). In addition to the known etiology, autoimmune disorders may be a pathologic mechanism for POI. MATERIALS AND METHODS Our study was a prospective controlled trial. Twenty women with POI, reasons other than autoimmune excluded, were enrolled in this study. The control ...
متن کاملAdolescent Premature Ovarian Insufficiency Following Human Papillomavirus Vaccination
Three young women who developed premature ovarian insufficiency following quadrivalent human papillomavirus (HPV) vaccination presented to a general practitioner in rural New South Wales, Australia. The unrelated girls were aged 16, 16, and 18 years at diagnosis. Each had received HPV vaccinations prior to the onset of ovarian decline. Vaccinations had been administered in different regions of ...
