Existence of Inhibin ?-Subunit Gene Mutation in a Population of Iranian Women with Premature Ovarian Failure
Authors
Abstract
Premature ovarian failure (POF) is characterized by hypergonadotropic amenorrhea, before the age of 40, for which the Inhibin α-subunit (INHα) gene is proposed as a candidate gene, due to its role in negative feedback control of FSH. In this study we aimed at demonstrating the candidate mutation as a gene variation associated with POF in Iranian population. Materials & Methods: Using DNA sequencing, DNA samples of 24 women with POF and 24 controls, aged below 40 years, were screened for mutations in the Inhibin gene. Results: The 769G→A mutation in exon 2 of the Inhibin-α gene was found in four out of 24 idi-opathic POF patients. Conclusion: The results obtained in this study have shown that this variation is more frequent in patients with POF than in normal fertile pop-ulations of Iran.
