Genetics and Epigenetics of Polycystic Ovary Syndrome

Abstract

Polycystic ovary syndrome (PCOS) is one of the most common endocrinological and reproductive disorders in women of reproductive age with a global prevalence rate of 5–20%. It is a clinically and genetically heterogeneous disorder. There have been multiple reports from independent research groups from different ethnicities that a variety of factors, including genetics and epigenetics, significantly contribute to the etiopathogenesis of PCOS. GWAS, twin studies, and genotype-phenotype association studies have resulted in the identification of more than a dozen candidate genes/loci with PCOS. In the proposed book chapter, we aim to provide insight and discuss the role of various genetic and epigenetic elements that are responsible for PCOS globally and in India. This book chapter should serve as a reference to all the basic researchers and healthcare professionals on the genetics and epigenetics of PCOS.
