Iatrogenic, autoimmune, and genetic causes are known to be involved in POI, but nearly 70% of all forms remain unexplained. Recent and new genetic analyses promote the identification of new candidate genes. The aim of this study was to evaluate the contribution of array-CGH and next-generation sequencing (NGS) in the diagnosis of POI. Study design: Twenty-eight idiopathic POI patients with primary or secondary amenorrhea underwent genetic screening by array-CGH and NGS using a custom capture design of 163 genes known or suspected to be involved in ovarian function. The clinical, biological, and ultrasound characteristics of the patients were also recorded. Results: Four of the twenty-eight patients had primary amenorrhea (14.3%), and twenty-four (85.7%) had secondary amenorrhea, with an average age at diagnosis of 27.7. Eleven patients (39.3%) had a family history of POI. Our study identified a genetic anomaly in 16 of 28 patients (57.1%): one patient carried a causal copy number variation (CNV), eight patients carried a causal single nucleotide variation (SNV)\/indel variation (28.6%), and seven other patients carried variants of uncertain significance. Conclusions: Our study was the first to combine genetic analyses by using both array-CGH and NGS in the same patients. It confirmed the usefulness of both analyses in the identification of pathogenic variations responsible for idiopathic POI. Early genetic diagnosis plays a major role in the management of complications and the screening of relatives.<\/jats:p>","DOI":"10.3390\/genes16030251","type":"journal-article","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T07:46:57Z","timestamp":1740383217000},"page":"251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Genetics Investigation of Idiopathic Premature Ovarian Insufficiency: Contribution of Array-CGH and Next-Generation Sequencing"],"prefix":"10.3390","volume":"16","author":[{"given":"Claire","family":"Cozette","sequence":"first","affiliation":[{"name":"Reproductive Medicine and Biology Department, CECOS of Picardy, Amiens University Hospital, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathilde","family":"Pujalte","sequence":"additional","affiliation":[{"name":"Department of Constitutional Genetics, Amiens University Hospital, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"No\u00e9mie","family":"Celton","sequence":"additional","affiliation":[{"name":"Department of Constitutional Genetics, Amiens University Hospital, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorian","family":"Bosquet","sequence":"additional","affiliation":[{"name":"Reproductive Medicine and Biology Department, CECOS of Picardy, Amiens University Hospital, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henri","family":"Copin","sequence":"additional","affiliation":[{"name":"Reproductive Medicine and Biology Department, CECOS of Picardy, Amiens University Hospital, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosalie","family":"Cabry","sequence":"additional","affiliation":[{"name":"Reproductive Medicine and Biology Department, CECOS of Picardy, Amiens University Hospital, 80000 Amiens, France"},{"name":"Peritox UMR_I 01, CURS, Jules Verne University of Picardy, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Loic","family":"Gar\u00e7on","sequence":"additional","affiliation":[{"name":"Department of Constitutional Genetics, Amiens University Hospital, 80000 Amiens, France"},{"name":"HEMATIM UR4666, CURS, Jules Verne University of Picardy, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moncef","family":"Benkhalifa","sequence":"additional","affiliation":[{"name":"Reproductive Medicine and Biology Department, CECOS of Picardy, Amiens University Hospital, 80000 Amiens, France"},{"name":"Peritox UMR_I 01, CURS, Jules Verne University of Picardy, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7934-6826","authenticated-orcid":false,"given":"Florence","family":"Scheffler","sequence":"additional","affiliation":[{"name":"Reproductive Medicine and Biology Department, CECOS of Picardy, Amiens University Hospital, 80000 Amiens, France"},{"name":"Peritox UMR_I 01, CURS, Jules Verne University of Picardy, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5704-6830","authenticated-orcid":false,"given":"Guillaume","family":"Jedraszak","sequence":"additional","affiliation":[{"name":"Department of Constitutional Genetics, Amiens University Hospital, 80000 Amiens, France"},{"name":"HEMATIM UR4666, CURS, Jules Verne University of Picardy, 80000 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Eshre Guideline Group on POI, Webber, L., Davies, M., Anderson, R., Bartlett, J., Braat, D., Cartwright, B., Cifkova, R., de Muinck Keizer-Schrama, S., and Hogervorst, E.
