Results of multiple sclerosis :
| Risk Type | Disease risk |
| Main Result | Positive |
| Result | Under dominant model, IL1RNmspa1 11,100 TC + CC genotype was significantly associated with a decreased MS risk.The heterozygous genotype TC of the variant was also associated with a significant decreased MS risk but under codominant model.Frequencies of IL1RNmspa1 11,100C variant alleles were significantly decreased in MS patients compared to control. |
| Mechanism/Pathway | The autoimmune inflammatory response in MS is initiated by autoreactive T lymphocytes that mount exaggerated immune responses against autoantigens of the CNS and promote inflammation, demyelination, gliosis and neuroaxonal degeneration.However, it has been demonstrated that lymphocyte migration across the blood–brain barrier is regulated by activation of proinflammatory cytokines, which showed upregulated levels in cerebrospinal fluid (CSF) and sera of MS patients. |
