Genetic prediction of blood cell reactivity and its potential causal influence on bone continuity and density disorders

Animal Models and Experimental Medicine, EarlyView.
We applied Mendelian randomization to explore causal links between blood cell traits and skeletal disorders. Using genetic instruments from large‐scale summary statistics, we assessed effects on bone continuity, density, and structural integrity. Sensitivity and reverse analyses confirmed robust associations, highlighting potential shared biological ...

Causal and mediating effects of lipid and facial aging: association study integrating GWAS, eQTL, mQTL, and pQTL data

Lipids in Health and Disease
Background Increasing evidence suggests a potential causal association between lipid levels and facial aging. The aim of this study was to investigate the relationship between levels of specific lipids and facial aging via Mendelian randomization methods.

Mendelian Randomization

Causal claims from observational epidemiological studies are influenced by reverse causation and confounding. Mendelian randomization assesses whether genetic predictors of a risk factor (such as alcohol consumption) are associated with risk of a disease outcome (such as stroke).

Longitudinal Phenotypic Trajectories in GNAO1‐Related Disorders: Defining Disease Progression and Clinical Profiles

Annals of Neurology, EarlyView.
Objective Pathogenic variants in GNAO1 cause a spectrum of epilepsy, movement disorders, and developmental impairment. Clinical heterogeneity complicates prognosis and therapeutic development. We present the first longitudinal natural history study of GNAO1‐related disorders (GNAO1‐RD) to delineate phenotypic trajectories. Methods Sixty‐six individuals

Genetic‐Proteomic Integration Identifies Predictive Plasma Proteins for Multiple Sclerosis

Annals of Neurology, EarlyView.
Objective Multiple sclerosis (MS) develops after a prolonged preclinical phase. Identifying circulating biomarkers that capture this early biology can improve risk stratification and guide intervention. We aimed to identify plasma proteins driving MS susceptibility using large‐scale proteogenomic integration and to evaluate their prediagnostic ...

Increased plasma microbial tDR‐1 in at‐risk individuals is associated with decreased conversion to clinical rheumatoid arthritis and reduces an in vitro macrophage type 1 interferon response

Arthritis &Rheumatology, Accepted Article.
Background Microbial small RNAs (sRNAs) can regulate human genes. Higher plasma concentrations of microbial tRNA‐derived RNA‐1 (tDR‐1) were previously associated with lower rheumatoid arthritis (RA) disease activity. This study examined whether tDR‐1 concentrations differ in anti‐cyclic citrullinated peptide‐3 positive (CCP3+) at‐risk individuals (ARI)

Mendelian randomization: Principles and methods [PDF]

Mendelian randomization (MR) is a methodology for evaluating causality in observational studies. MR tries to find the fact that genotypes are not susceptible to reverse causation and confounding based on Mendel's law of inheritance.
