Abstract
Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting a significant population of women of reproductive age group worldwide. Due to the complex pathophysiology and overlapping symptoms, this disorder is often difficult to diagnose. Genome-wide association studies have identified several new risk loci and candidate genes for PCOS. However, currently, there are no standard genetic markers for PCOS susceptibility testing owing to the inconsistent findings. Despite the advent of the genomic era, the challenge to identify and pinpoint the heritable genetic basis of PCOS still exists. This mini-review explores the basic definition and phenotypes of PCOS, the different criteria for the diagnosis, the incidence, gestational complications associated with it, the basis of genetic heritability, and the influence of various gene polymorphisms. Also, this review briefly summarises the reports of genome-wide association studies conducted to identify candidate genetic markers to aid in understanding the complex pathophysiology of PCOS.
