Mendelian randomization provides no evidence for a causal role of serum urate in increasing serum triglyceride levels.

ABSTRACT:

Background

Triglycerides and their lipoprotein transport molecules are risk factors for heart disease. Observational studies have associated elevated levels of serum urate (SU) with triglycerides and risk of heart disease. However, owing to unmeasured confounding, observational studies do not provide insight into the causal relationship between SU and triglyceride. The aim of this study was to test for a causal role of SU in increasing triglyceride using Mendelian randomization that accounts for unmeasured confounding.

Methods and results

Subjects were of European ancestry from the atherosclerosis risk in communities (n=5237) and Framingham heart (n=2971) studies. Mendelian randomization by the 2-stage least squares regression method was done with SU as the exposure, a uric
