Abstract :
Background: Polycystic ovary syndrome (PCOS), a multifaceted condition, often has salient features like insulin resistance (IR). Abnormal alternation in insulin synthesis and function usually alters PCOS expressivity by deviating molecular and biochemical activity underlying this pathophysiology.
Aims: This review intends to unveil the molecular basis of the genetic polymorphism of IR and its correlation with PCOS. It also highlights the existing methods of IR estimation.
Material and Methods: Searching of different articles using keywords including PCOS, IR, and polymorphism in various databases was performed to illustrate the review article.
Conclusion: POCS, and IR are complex and multifactorial conditions in terms of the contributing factors, their interactions, and expressivity. Further studies on diversified genotype responses to environmental and ethnic variances are required for precise understanding.
Key Messages: Insulin resistance (IR) and polycystic ovary syndrome (PCOS) are intricately interacted conditions that abnormally alter functions from genetic to organ system level. Complex gene-environment interactions make it difficult to understand the etiology and manifestation, and so diagnosis and management approaches of the heterogeneous pathophysiology are not foolproof. Further studies on genetic susceptibility related to ethnic distribution are essential for the implementation of personalized treatment of IR and PCOS.
