Mendelian randomization and summary data-based Mendelian randomization were applied to assess the potential causal associations between selenoproteins and AD. To further confirm these genetic associations at the clinical level, we conducted a case-control study to evaluate the levels of four differentially expressed selenoproteins in peripheral blood in individuals with AD and cognitively normal controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our analysis revealed that four selenoproteins, including selenoprotein S (SEPH2) and selenoprotein M (SELENOM), glutathione peroxidase 4 (GPX4) and thioredoxin reductase 2 (TXNRD2), were correlated with a decreased risk of AD. The levels of GPX4, SELENOM, and TXNRD2 were found to be significantly downregulated in AD patients compared to controls in the case-control validation study, supporting the change identified in our genetic analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study provides genetic and clinical evidence that specific selenoproteins are associated with a decreased risk of AD.
