A new study has added further weight to the theory that vitamin D deficiency plays a part in the development of multiple sclerosis (MS).
Researchers at Oxford University looked at thousands of genes for signs of vitamin D binding directly and possible changing the way genes work.
It was discovered that there are hundreds of genes which could be affected in this way, while many of the genes are known to be involved with the development of multiple sclerosis.
Reacting to the news, the MS Society's head of biomedical research Dr Doug Brown said: "We are seeing mounting evidence that vitamin D deficiency plays a role in the development of MS and this latest study is an encouraging milestone.
"We are now exploring ways of moving this exciting area of research forward."
The charity recently called for people living with this disease to participate in a new survey, which will seek to inform the government on what life is like for people claiming disability allowances, and how the situation could be improved.
