Insulin resistance is a core feature of polycystic ovary syndrome (PCOS). Phosphatidylinositol (PI) 3-kinase is an important enzyme in the early insulin signaling cascade and plays a key role in insulin-mediated glucose transport. In its regulatory subunit, p85alpha, there is a common amino acid substitution (the Met326Ile polymorphism), and this amino acid may be crucial for the function of the p85alpha regulatory subunit and PI3-kinase.
