Literature information of multiple sclerosis :

Pubmed ID	8556305
Year	1995
Title	Evidence of Linkage between Susceptibility to Multiple Sclerosis and HLA-Class II Loci in Italian Multiplex Families

Results of multiple sclerosis :

Risk Type	Disease risk
Main Result	MS susceptibility is conferred by HLA class II alleles
Result	Evidence supporting the existence of linkage between MS susceptibility and the HLA class II loci DRB1, DQA1 and DQB1 was provided using two non-parametric tests, affected sib-pair analysis, and affected-pedigree-member (APM) analy- sis.
Mechanism/Pathway	MS susceptibility is conferred by HLA class II alleles according to a low-penetrance autoso- mal recessive mode of inheritance.
