Genetics

Multiple sclerosis is a multifactorial autoimmune disease shaped by interactions among genetic, environmental, and immunological factors. This blog post explores scientific evidence linking vitamin D status and vitamin D-related genetic variants to susceptibility to multiple sclerosis, with particular attention to genes involved in vitamin D synthesis, metabolism, transport, and signaling. It examines key candidates such as VDR, CYP27B1, CYP2R1, CYP24A1, and GC, while highlighting the inconsistent findings reported across different populations. Overall, the research suggests that vitamin D-related genetics may contribute to MS risk as part of a broader polygenic and environmental network, although further large-scale studies are required before these associations can be translated into clinical practice.
