Vitamin D concentration, obesity, and risk of diabetes: a mendelian randomisation study

Genetic variants associated with low plasma 25(OH)D concentrations are associated with type 2 diabetes and low plasma 25(OH)D concentrations might be a modest mediator between obesity and increased risk of diabetes.However, as findings for DHCR7 were not statistically significant, our results require independent confirmation (The Lancet Diabetes & Endocrinology)
