Tumor necrosis factor-alpha promoter polymorphisms are associated with idiopathic primary ovarian insufficiency in Korean women

The TNF-α -1031C and -238A alleles had strong association with POI. The TNF-α -308A allele showed limited significance for POI risk with the presence of the -1031T allele. Our data suggest that the minor alleles of TNF-α promoter polymorphisms may increase POI risk in Korean women.
