Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system (CNS). A growing body of evidence supports a role for vitamin D in MS aetiology. Vitamin D binding protein (DBP) is the major plasma carrier of vitamin D metabolites and genetic differences in DBP gene have been found to influence vitamin D levels. We review here(More)
Multiple Sclerosis (MS) is the most common demyelinating disease of the central nervous system. Although the etiology and the pathogenesis of MS has been extensively investigated, no single pathway, reliable biomarker, diagnostic test, or specific treatment have yet been identified for all MS patients. One of the reasons behind this failure is likely to be(More)
BACKGROUND Multiple sclerosis (MS) is determined by interactions between genes and environment and the influence of vitamin D adequacy has been proposed. Previous studies have shown that serum 25-hydroxyvitamin D (25(OH)D) levels are genetically influenced. Polymorphisms in vitamin D pathway genes are candidates for association with MS susceptibility.

Our aim was to investigate whether there is a season-of-birth effect in anorexia nervosa. In a meta-analysis, we compared the distribution of anorexia births (n = 1293) from four independent UK cohorts to that of the general UK population (n = 21 914 037), using both the Walter & Elwood seasonality and chi-squared tests. We found an excess of anorexia(More)
A role for T cells in the pathogenesis of multiple sclerosis (MS) is well supported, evidenced by myriad immunological studies, as well as the unequivocal genetic influence of the major histocompatibility complex (MHC). Despite many attempts, no convincing genetic associations have been made between T-cell receptor (TCR) gene loci and MS. However, these(More)
Multiple sclerosis (MS) is a complex trait with a significant genetic component. Recent work has implicated the ST8SIA1 gene, encoding a ganglioside synthase, in susceptibility to the disease, perhaps with a parent-of-origin effect. In this investigation of 1318 MS patients from 756 Canadian families, we analysed the transmission of the four single(More)
determining susceptibility to a wide range of psychiatric disorders such as schizophrenia, bipolar disorder, major depression and suicidal behaviour. 1,2 This hypothesis has been investigated in people with anorexia nervosa and other eating disorders; 3–8 however, although an excess of spring births has been suggested, results are conflicting and rarely(More)
