Abstract
Both genetic and environmental risk factors may contribute to risk of multiple sclerosis
(MS) in children. Genetic risk factors include the presence of the human leukocyte
antigen (HLA)-DRB1*1501 allele and other non-HLA single nucleotide polymorphisms.
Environmental risk factors include parental smoking, low serum vitamin D levels, and
prior exposure to Epstein–Barr virus. Some of these risk factors not only confer increased
susceptibility to MS but may also alter the course of the disease. How different risk
factors interact is a growing area of research. In this review, we examine the current
literature regarding the genetic and environmental risk factors for MS in children.
