OBJECTIVE Variation in the major histocompatibility complex (MHC) on chromosome 6p21 is known to influence susceptibility to multiple sclerosis with the strongest effect originating from the HLA-DRB1 gene in the class II region. The possibility that other genes in the MHC independently influence susceptibility to multiple sclerosis has been suggested but(More)
Individual genotyping of the 10 most promising markers identified in our previously reported screen for linkage disequilibrium (LD) in multiple sclerosis identified a number of effects which confound the analysis and are of general importance in the interpretation of results obtained using microsatellite markers typed in pooled DNA. In order to identify and(More)
Osteopontin transcription is increased in the central nervous system of patients with multiple sclerosis and rats with experimental allergic encephalomyelitis; where expression correlates with disease severity. We typed four single nucleotide polymorphisms located in exons 6 and 7 of the osteopontin gene in a large cohort of 1056 multiple sclerosis patients(More)
BACKGROUND By comparison with the neighboring island of Sicily, the frequency of multiple sclerosis (MS) in Malta is remarkably low. METHODS To explore whether the relative rarity of MS in Malta might be the result of lower population frequencies of major histocompatibility complex susceptibility alleles, we genotyped the HLA-DRB1 locus in 77 Maltese-born(More)
By combining all the data available from the Genetic Analysis of Multiple sclerosis in EuropeanS (GAMES) project, we have been able to identify 17 microsatellite markers showing consistent evidence for apparent association. As might be expected five of these markers map within the Major Histocompatibility Complex (MHC) and are in LD with HLA-DRB1.(More)
CD24 is expressed on a broad range of cells in the immune and central nervous systems and appears to be required for development of experimental autoimmune encephalomyelitis in mice. Association of a CD24 Ala/Val coding polymorphism with susceptibility to and progression of multiple sclerosis was recently reported. We typed this coding polymorphism in a(More)
P-Selectin (SELP) and P-selectin glycoprotein ligand-1 (SELPLG) constitute a receptor/ligand complex involved in the recruitment of activated lymphocytes, a critical event in the pathogenesis of multiple sclerosis (MS). In order to determine whether genetic variation in these pivotal molecules influences susceptibility to MS, we genotyped 214 Italian(More)
