Genetic Research Yields Connections Between Preeclampsia and Babies' Genetic Makeup
In a groundbreaking international genetic study, researchers have discovered that a potentially dangerous condition known as preeclampsia, which can occur during pregnancy, is linked to a baby's DNA. This groundbreaking finding was published in the journal Nature Genetics.
Led by first author Dr. Linda Morgan of the University of Nottingham in the U.K., the team analyzed DNA samples from over 4,000 children born to mothers who developed preeclampsia and over 300,000 whose mothers did not. This extensive investigation, which spanned 5 years, was carried out in Iceland, Norway, Finland, and the U.K.
Preeclampsia presents as a sudden increase in a pregnant woman's blood pressure during the 20th week, accompanied by increased protein in her urine and swollen hands and face. If left untreated, it can lead to severe health complications for both the woman and her baby. The condition affects around 5 percent of pregnancies and is a leading cause of pregnancy- and birth-related deaths.
In the past, studying preeclampsia has been challenging due to its onset during the formation of the placenta. However, this genome-wide association study (GWAS) allowed the researchers to look for clues in the mother's, father's, and their baby's DNA. While previous GWAS analyses of preeclampsia have been done, they only focused on the DNA of the mothers.
The GWAS analysis carried out at the Wellcome Trust Sanger Institute in Cambridge, U.K., and deCODE Genetics in Reykjavik, Iceland, identified two previously unknown DNA variants that were significantly linked to preeclampsia. These variants are close to a gene called FLT1 that codes for a cell-surface receptor known to be involved in the creation of new blood vessels. One form of FLT1 has been linked to the development of preeclampsia before. If placental levels of the associated protein become too high, they enter the pregnant woman's bloodstream and can damage her blood vessels, resulting in high blood pressure and damage to her liver, kidneys, and brain.
Dr. Morgan and her team believe their study is the first genetic study of preeclampsia to focus on the DNA of the offspring. They are now analyzing the genomes of another 4,220 babies in Kazakhstan and Uzbekistan to find out if these same DNA variants are present. If confirmed, these findings could pave the way for more effective prevention and treatment of preeclampsia in the future, improving the outcome of pregnancy for both mother and child.
Recent genetic studies on preeclampsia have also identified genes like STOX1 and APOL1 that contribute to the development of the condition by affecting placental development and function, as well as angiogenic processes. These genetic factors, combined with environmental and clinical risk factors, play a crucial role in causing preeclampsia. Understanding these interactions could help improve the diagnosis and management of this potentially life-threatening condition.
