High-Throughput Sequencing to Identify Monogenic Etiologies in a Preselected Polycystic Ovary Syndrome Cohort

The study utilized high-throughput sequencing to identify rare genetic variants in a cohort of 53 women with polycystic ovary syndrome (PCOS). It found that 18.8% of the cases had rare genetic variants potentially linked to PCOS, including pathogenic and likely pathogenic variants in genes such as INSR, LMNA, PIK3R1, and DLK1. The findings suggest a genetic basis for PCOS in a subset of patients, particularly those with severe insulin resistance, and highlight the importance of genetic screening in understanding and managing the condition.
