Genome-wide lipidomic profiling reveals causal lipid species as targets for inguinal hernia risk.

ABSTRACT: Inguinal hernia (IH) is a common condition with a substantial health burden and emerging evidence suggests that lipid metabolism-related indicators may contribute to its risk. However, the exact role of specific lipid types in causing IH is still unclear. This study aims to investigate whether any of 179 distinct lipid species have a causal impact on IH risk using causal inference. We applied a two-sample Mendelian randomization (MR) framework, integrating lipidomic genome-wide association studies (GWAS) data from 7,174 Finnish individuals with IH summary statistics from the UK Biobank (16,749 cases and 439,599 controls). Linkage disequilibrium pruning and genome-wide significance (P < 5E-8) were used to choose genetic instruments. Primary causal estimates were derived with inverse-varianc
