Inflammation’s Causal Role: New Mendelian Randomization Evidence Emerges
Key Highlights
Medicine · Public Health · Genetic Epidemiology
A new study employing multivariable Mendelian randomization (MVMR) provides a refined estimate of the causal effects of C-reactive protein (CRP) on a range of disease and health outcomes. Unlike univariable analyses that suggested CRP causally influences nine conditions, the MVMR approach, which adjusts for a broad set of computationally identified heritable confounders, confirmed causal effects on only four: HDL cholesterol (negative), glycated hemoglobin (positive), rheumatoid arthritis (risk-increasing), and schizophrenia (risk-decreasing). For a public health researcher and laboratory scientist developing vaccine platforms, this rigorous evidence clarifies the specific, inflammation-mediated pathways through which CRP—a key innate immune marker—contributes to disease, helping to distinguish true targets for intervention from confounded associations.
