Literature information of multiple sclerosis :

Pubmed ID	8244781
Year	1993
Title	The influence of HLA-DR and -DQ alleles on progression to multiple sclerosis following a clinically isolated syndrome

Results of multiple sclerosis :

Risk Type	Disease risk
Main Result	Negative
Result	Conversion to MS was positively associated with the DRB1*1501.DQA1*0102.DQBl*0602 haplotype, but the influence of HLA was only significant in patients with disseminated brain lesions at presentation (MRI positive); MS developed in 86% of MRI-positive, DRBl*1501-positive patients compared with 55% of MRI -positive, DRB 1 * 1501-negative patients.
Mechanism/Pathway	N/A
