A groundbreaking first-of-its-kind Indian genome-wide study has identified 21 genetic regions linked to endometriosis, providing crucial evidence of genetic susceptibility in Indian women.

  • India's first genome-wide study identified 21 suggestive genetic regions associated with endometriosis.
  • The strongest genetic signal was found near the LINC00415/SHISA2 region on chromosome 13.
  • The findings aim to address the underrepresentation of South Asian populations in genetic research.
  • Results are currently for research purposes and not yet for individual clinical diagnosis.

For decades, women suffering from endometriosis—a condition where tissue similar to the uterine lining grows outside the uterus—have endured debilitating period pain, chronic pelvic pain, and infertility. Often, these women report similar symptoms in their mothers or sisters. Now, India’s first genome-wide study has provided scientific weight to these observations, suggesting that genetic susceptibility plays a significant role in the Indian population.

Breakthrough Genetic Findings

Published in Scientific Reports, the study identified 21 suggestive genetic regions associated with endometriosis in Indian women. A standout discovery was the strong signal located near the LINC00415/SHISA2 region on chromosome 13. While researchers emphasize that these findings are not yet ready for clinical risk prediction, they establish a vital foundation for understanding the disease's biological pathways in South Asians.

Why This Matters

BozokMedia analysis shows that the vast majority of existing endometriosis research has been conducted on populations of European ancestry. This creates a significant 'knowledge gap' for the rest of the world. By establishing a dedicated Indian genetic dataset, this study ensures that medical advancements in women's health are inclusive and effective for the South Asian demographic, rather than being based solely on Western genetic profiles.

"When I started working on endometriosis research nearly two decades ago, I was struck by how many women lived for years with severe pain before receiving a diagnosis. Now, we have the tools to understand the familial patterns I observed." - Dr. Rahul Gajbhiye

The Journey Toward a Genomic Dataset

The research was led by Dr. Rahul Gajbhiye, Principal Investigator and Head of the Clinical Research Laboratory at ICMR–National Institute for Research on Women’s Health (ICMR–NIRWoH), Mumbai. The initiative, known as Endometriosis Clinical and Genetic Research in India (ECGRI), involved a massive collaborative effort across 18 centers in India. This study combined clinical information with genomic data to create one of the largest and most comprehensive datasets of its kind in the country.

Global Impact and Public Health

Endometriosis affects approximately 10% of women of reproductive age globally. In India, the challenge is compounded by limited awareness and the tendency to normalize menstrual pain. As the World Health Organization (WHO) works on new management guidelines, this Indian study provides the necessary population-specific evidence to help move toward earlier diagnosis and more personalized treatment options.

Did You Know?: Endometriosis is often misdiagnosed or diagnosed years late because many healthcare providers mistakenly view severe menstrual pain as 'normal.'

Frequently Asked Questions

1. Can I use this study to check my personal risk of endometriosis?
No, the current findings are intended for scientific research and cannot yet be used for individual clinical testing or risk assessment.

2. Why was this study specifically needed for India?
Most genetic studies on endometriosis focus on European populations. This study provides the essential South Asian data needed to understand how the disease manifests in Indian women.
