Association between 25(OH) vitamin D and multiple sclerosis: cohort, shared genetics, and Causality.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc in the context of multiple sclerosis, published as an observational study.

This study used GWAS datasets to investigate genetic associations between 25OHD and MS.

The researchers utilized a large-scale prospective cohort to evaluate serum 25OHD levels and MS risk.

Who Took Part

PubMed indexes the participants as adults and middle-aged adults, both men and women.

Stratified LDSC estimated tissue-specific and cell-specific heritability enrichment, and multi-trait co-localization analysis identified shared immune cell subsets.

Bidirectional Mendelian Randomization (MR) assessed the causal association between 25OHD and MS risk.

How the Study Was Run

Linkage Disequilibrium Score Regression (LDSC) assessed genetic correlations between 25OHD levels and MS.

Cross-trait genome-wide pleiotropy analysis revealed shared genetic loci.

MAGMA analysis identified pleiotropic genes, enriched tissues, and gene sets.

What Was Measured

The subject headings attached to it are Multiple Sclerosis, Vitamin D, Genome-Wide Association Study, Mendelian Randomization Analysis, Cohort Studies, Polymorphism, Single Nucleotide and Genetic Predisposition to Disease.

The authors tagged it with the keywords Genetic overlap.
