The miR-449b polymorphism, rs10061133 A>G, is associated with premature ovarian insufficiency.

Objective:To determine if the miR-449b polymorphism, rs10061133 A>G, is associated with premature ovarian insufficiency (POI) pathogenesis.Methods:From January 2011 to December 2014, a total of 148 individuals with POI and 225 age-matched controls were collected from the Center for Reproductive Medicine, 1st Affiliated Hospital of Anhui Medical University (Hefei, China). Genotyping of miR-449b rs1006113 was performed using matrix-assisted laser desorption ionization time-of-flight-based mass spectrometry.Results:Rs10061133 A>G is a highly conserved SNP locus in the mature area of miR-449b. Association analysis shows that the rs10061133 AA genotype is a risk factor for POI.Conclusions:Our study provides the first evidence that the miR-449b rs10061133 AA genotype is associated with POI risk.
