    Objective: To investigate the causal relationship between lipidome and Malignant melanoma of skin (MMOS), while identifying and quantifying the role of metabolites as potential mediators. Methods: A two-sample Mendelian randomization (MR) analysis of lipid species (n=7174) and MMOS was performed using pooled data from genome-wide association studies (GWAS). In addition, we quantified the proportion of metabolite-mediated lipidome effects on MMOSby two-step MR. Results: This study identified potential causal relationships between 11 lipids and MMOS, and 40 metabolites and MMOS, respectively. Phosphatidylethanolamine (18:0_18:2) levels mined from 179 lipids by MR Analysis increased the risk of MMOS (OR: 1.962; 95%CI:1.298,2.964; P=0.001). There is no strong evidence for a relationship between genetically predicted MMOS and Phosphatidylethanolamine (18:0_18:2) levels (P=0.628). The proportion of gene predictions for Phosphatidylethanolamine (18:0_18:2) levels mediated by 1-stearoyl-GPI (18:0) levels was 12.40%. Conclusion: This study identifies 1-stearoyl-GPI (18:0) levels as a potential mediator that may mediate the causal relationship between Phosphatidylethanolamine (18:0_18:2) levels and MMOS, This provides direction for the investigation of MMOS, but further research of other possible potential mediators is still needed.
