Getting to grips with migraine
Date:6/23/2013

genetic regions associated with migraine are interconnected and could potentially be disrupting the internal regulation of tissue and cells in the brain, resulting in some of the symptoms of migraine.

"We would not have made discoveries by studying smaller groups of individuals," says Dr Gisela Terwindt, co-author from Leiden University Medical Centre. "This large scale method of studying over 100,000 samples of healthy and affected people means we can tease out the genes that are important suspects and follow them up in the lab."

The team identified an additional 134 genetic regions that are possibly associated to migraine susceptibility with weaker statistical evidence. Whether these regions underlie migraine susceptibility or not still needs to be elucidated. Other similar studies show that these statistically weaker culprits can play an equal part in the underlying biology of a disease or disorder.

"The molecular mechanisms of migraine are poorly understood. The sequence variants uncovered through this meta-analysis could become a foothold for further studies to better understanding the pathophysiology of migraine" says Dr Kri Stefnsson, President of deCODE genetics.

"This approach is the most efficient way of revealing the underlying biology of these neural disorders," says Dr Mark Daly, from the Massachusetts General Hospital and the Broad Institute of MIT and Harvard. "Effective studies that give us biological or biochemical results and insights are essential if we are to fully get to grips with this debilitating condition.

"Pursuing these studies in even larger samples and with denser maps of biological markers will increase our power to determine the roots and triggers of this disabling disorder."
