TLDR High levels of TNF-α may contribute to obesity and insulin resistance in PCOS, but not due to the C850T genetic variation.
The study from 2014 examined the involvement of Tumor Necrosis Factor-alpha (TNF-α) in the development of insulin resistance and obesity in 204 patients with Polycystic Ovarian Syndrome (PCOS) compared to 204 healthy controls. Results showed that PCOS patients had significantly higher body mass index (BMI), waist circumference, waist-to-hip ratio, fasting insulin, homeostatic model assessment (HOMA) score, and serum TNF-α levels. However, the C850T (rs1799724) polymorphism in the TNF-α gene was not found in the PCOS group, while it had a 9% frequency in the control group. The study concluded that the TNF-α system might play a role in the pathogenesis of hyperandrogenism, obesity, and insulin resistance in PCOS, but this is independent of the C850T polymorphism in the population studied.
