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.
