Vitamin D and MS

February 12, 2009

Researchers found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis (MS).

The research suggests vitamin D deficiency during pregnancy and the early years of life may increase the risk of the child developing MS later in life.

For some time, scientists have known that environmental risk and genes determine MS risk. This new study identifies a direct link between Vitamin D and a gene variant known as DRB1*501.

"In people with the DRB1 variant associated with MS, it seems that vitamin D may play a critical role," study co-author Dr. Julian Knight was quoted as saying. "If too little of the vitamin is available, the gene may not function properly."
