The largest genetics-based study of multiple sclerosis ever conducted is casting significant doubt on a controversial theory that the disease is a vascular condition caused by blocked neck veins.
The largest genetics-based study of multiple sclerosis ever
conducted is casting significant doubt on a controversial theory
that the disease is a vascular condition caused by blocked neck
veins. The study identified more than two dozen new genetic
variants common to people with MS and found the majority of genes
involved are pivotal to the immune system.
While the discovery is important, the large number of genes
implicated in MS also indicates how complex it is and how much more
work remains to be done, said Amit Bar-Or,
associate professor of neuroimmunology and director of the
experimental therapeutics program at the Montreal Neurological
Institute and Hospital.
“It hasn’t made things any simpler. It’s made them more
complicated,” he said. “We are several steps away from translating
this to effective therapy but it’s an important step.
