Largest migraine-genetics study to date could inspire new treatments

19/04/2022

Millions of people around the world suffer with migraines on a regular basis. These debilitating headaches can last for days at a time and, in severe cases, prevent people from going about their daily lives, including working and studying. While there are drugs to treat migraine headaches and others to prevent their onset, the cause of migraines remains unknown. The leading theory is that migraines are a neurovascular condition that involves an interaction between the blood vessels in the head and the brain itself. Now, the largest study of migraines to date has uncovered 123 genetic regions, or loci, that are associated with the condition — 86 of which were previously unknown. The research, which involved analyzing the genomes of 102,084 people with migraine and those of 771,257 controls who do not have the condition, has trebled the known genetic risk factors for the condition. “In addition to implicating tens of new regions of the genome for more targeted investigation, our study provides the first meaningful opportunity to evaluate shared and distinct genetic components in the two main migraine subtypes,” says first author Heidi Hautakangas, Ph.D., from the Institute for Molecular Medicine Finland at the University of Helsinki. The study is published in Nature Genetics. *Image by StockSnap from Pixabay
