A groundbreaking study analyzing the genetic data of approximately 300,000 women has shed new light on the complex genetic factors influencing a wide range of female reproductive health diagnoses. The research, published in Nature Medicine, represents a significant step forward in understanding the biological underpinnings of conditions often under-researched.
The genome-wide association study meta-analysis, coordinated by Triin Laisk, associate professor of genomics and reproductive genetics at the University of Tartu, utilized data from the Estonian Biobank and FinnGen, examining 42 distinct female reproductive health diagnoses. “Women’s health has been an under-researched area for quite a long time, and we are truly delighted that it is now receiving this kind of coverage in Nature Medicine,” stated Laisk.
The study not only identified previously unknown genetic associations but also revealed shared genetic risk factors across various phenotypes. These shared factors provide crucial insights into fundamental processes such as reproductive tract development, folliculogenesis, and hormone regulation. Conversely, unique genetic associations illuminated disease-specific biological mechanisms.
“Identifying previously undescribed associations provides information on the biological background of diseases and traits, which are a valuable input for, for example, drug development,” Laisk explained. For instance, the analysis of ovarian cysts identified genes linked to human folliculogenesis that were previously undescribed, potentially aiding in the development of in vitro fertilization treatments.
The research team had previously published findings on the genetics of ectopic pregnancy and endometrial polyps, highlighting the importance of focused studies on specific conditions.
Furthermore, the study demonstrated the potential of genetics in disease risk prediction. Using intrahepatic cholestasis in pregnancy (ICP), a rare liver disease, as an example, researchers found that a genetic risk score could effectively predict disease risk, enabling earlier identification of at-risk pregnancies. While ICP is not preventable, early diagnosis can mitigate potential complications.
A unique aspect of the study was the identification of population-specific genetic risk factors by analyzing Estonian and Finnish data, showcasing the unique value of the Estonian Biobank. The researchers have made the summary statistics of their analyses publicly available, facilitating future research in this critical area.
“This is a good example of how something that started as a student project can become a very important piece of research in the field, published in one of the best journals in the world,” said Laisk.
