Genetically identified mediators associated with increased risk of stroke and cardiovascular disease in individuals with autism spectrum disorder.

Growing evidence suggested that individuals with autism spectrum disorder (ASD) associated with stroke and cardiovascular disease (CVD). However, the causal association between ASD and the risk of stroke and CVD remains unclear. To validate this, we performed two-sample Mendelian randomization (MR) and two-step mediation MR analyses, using relevant genetic variants sourced from the largest genome-wide association studies (GWASs).

Identifying the genetic association between systemic lupus erythematosus and the risk of autoimmune liver diseases.

Background: Previous studies on the relationship between systemic lupus erythematosus (SLE) and autoimmune liver diseases (AILDs) are inconclusive. Therefore, we employed Mendelian randomization (MR) to explore the causal associations between SLE and AILDs.

Methods: A two-sample MR analysis was performed using summary-level statistics sourced from genome-wide association study (GWAS) datasets.

Particulate matter 2.5 causally increased genetic risk of autism spectrum disorder.
