Multiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially(More)
Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 × 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802(More)
Potentially causative missense variations in the ANG gene and a positive association with the synonymous rs11701-G substitution was detected mainly in Irish and Scottish ALS patients. We screened 262 Italian SOD1 negative ALS patients (250 sporadic) and 415 matched controls for sequence variations in the coding, 3'/5' UTR and 5' flanking (642 bp) regions of(More)
Mutations in the SOD1 gene exons and exon/intron boundaries were searched in 66 sporadic and 4 familial Italian ALS cases consecutively referred to our centre from different Italian regions. A mutation was found in three sporadic cases (4.5%): a new nonsense mutation in exon 5 (K136X) in a patient with a rapid and severe disease course and two previously(More)
To the Editor: In their recent communication, Aulchenko et al.1 suggested that the rs10492972[C] variant of KIF1B increases susceptibility to multiple sclerosis. In an attempt to replicate this observation, we genotyped this variant in eight case-control and three trio-family collections (in total 22,854 individuals were considered, comprising 8,391 cases,(More)
Several studies suggest that the histocompatibility complex (HLA) class I region harbours genes modulating multiple sclerosis (MS) susceptibility independently from the effect of class II alleles. A candidate gene in this region is MOG, encoding the myelin oligodendrocyte glycoprotein. A significant association with the missense variation V142L (rs2857766)(More)
Previous studies reported an association with multiple sclerosis (MS) of distinct HLA-class I markers, namely HLA-A*02, HLA-Cw*05 and MOG-142L. In this work, we tested the association with MS of A*02 and Cw*05 in 1273 Italian MS patients and 1075 matched controls, which were previously analyzed for MOG-142, and explored the relationship among these three(More)
Several single-nucleotide polymorphism (SNP) genome-wide association studies (GWASs) have been completed in multiple sclerosis (MS). Follow-up studies of the variants with the most promising rankings, especially when supplemented by informed candidate gene selection, have proven to be extremely successful. In this study we report the results of a(More)
BACKGROUND The T allele of rs9657904 within the CBLB gene was recently found to be significantly associated with multiple sclerosis (MS) in a genome-wide association study in Sardinia. OBJECTIVE To replicate this association in an independent population with a different genetic background. METHODS The rs9657904 variant was typed in a sample of 1435(More)
BACKGROUND The association of HLA A*02 with multiple sclerosis (MS) was recently confirmed by the authors, and it was observed that the combined presence of HLA Cw*05 significantly enhanced (threefold) the protective effect of HLA A*02. OBJECTIVES AND METHODS Since A*02-Cw*05 is carried by two HLA extended haplotypes characterised by the B*4402 and B*1801(More)
