ABSTRACT

Objective: Insulin resistance has been reported in up to 70% of women with polycystic ovary syndrome (PCOS). Physiologic and genetic data currently implicate post-insulin receptor signaling defects in substrates such as GSK3? . The AKT2 gene was chosen as a candidate for PCOS because its product affects glucose metabolism and mitogenic signaling, interacts with GSK3?, and mediates cell survival in the ovary.

Research Design and Methods: Subjects were recruited from the reproductive endocrinology clinic at the University of Alabama at Birmingham; controls were recruited from the surrounding community. 287 White women with PCOS and 187 White controls were genotyped for 4 SNPs in AKT2. Genotyping took place at Cedars-Sinai Medical Center in Los Angeles. Single nucleotide polymorphisms (SNPs) and haplotypes were tested for association with PCOS risk and phenotypic markers of PCOS.

Results: Minor allele carriers of SNPs rs3730051 and rs8100018 had increased odds of PCOS (OR=2.2, p=0.004 and OR=2.4, p=0.001, respectively). The haplotype T-G-C-T was significantly associated with PCOS (OR=2.0, p=0.01). Carriers of the risk haplotypes for both AKT2 and GSK3B had a further increased odds of PCOS (OR=3.1, p=0.005).

Conclusions: These data suggest that polymorphisms in two components of the insulin signaling pathway, AKT2 and GSK3B, are associated with PCOS. Presence of multiple lesions in a single pathway may confer increased risk.

Insulite Health, is committed to helping women reverse their symptoms of hormone imbalance. Scientific research has revealed that this imbalance can be a primary cause of many devastating health symptoms. Hormone Imbalance can also underlie the increased risk factors for PCOS (Polycystic Ovarian Syndrome) - a major source of serious diseases as well as cause of excess weight gain, adult acne, unwanted facial hair, depression, anxiety, and heartbreaking female infertility.
