Migraine gene

The issue of finding a possible migraine gene was sometimes discussed here, so I thought this information sounds very interesting: http://www.webmd.boots.com/migraines-headaches/news/20100927/migraine-gene-breakthrough-could-lead-to-new-treatments
Finding the gene is only the firts step to possibility of treatemnt, but since there have been no new developments in treating M since triptans, which was long time ago, we definitely need a new approach, so at least there is some hope for the future.
