Five new genetic regions associated with migraine identified

Washington, June 24 (ANI): Researchers have identified five genetic regions in the body that are associated with migraines.

The discovery could help scientists could help scientists understand what triggers the condition and eventually lead to treatments.

The team identified 12 genetic regions associated with migraine susceptibility. Eight of these regions were found in or near genes known to play a role in controlling brain circuitries and two of the regions were associated with genes that are responsible for maintaining healthy brain tissue. The regulation of these pathways may be important to the genetic susceptibility of migraines.

Migraine has recently been recognized as the seventh disabler in the Global Burden of Disease Survey 2010 and has been estimated to be the most costly neurological disorder. It is an extremely difficult disorder to study because no biomarkers between or during attacks have been identified so far.

"This study has greatly advanced our biological insight about the cause of migraine," says Dr Aarno Palotie, from the Wellcome Trust Sanger Institute. "Migraine and epilepsy are particularly difficult neural conditions to study; between episodes the patient is basically healthy so it's extremely difficult to uncover biochemical clues.

"We have proven that this is the most effective approach to study this type of neurological disorder and understand the biology that lies at the heart of it."

The team uncovered the underlying susceptibilities by comparing the results from 29 different genomic studies, including over 100,000 samples from both migraine patients and control samples.

They found that some of the regions of susceptibility lay close to a network of genes that are sensitive to oxidative stress, a biochemical process that results in the dysfunction of cells.

The team expects many of the genes at 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.

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. (ANI)
