We assessed the association between genetic variations, serum magnesium levels, and CKD risk in the general population.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n In this population-based prospective study (n=4047; mean age 53 years; 54% female; mean follow-up 12.5 years). Cox regression models evaluated the effects of hypomagnesemia on CKD risk. Genetic risk scores and mediation analyses were used to assess the direct and indirect effects of single-nucleotide polymorphisms (SNPs) on CKD development through magnesium levels. One-sample and two-sample Mendelian randomization (MR) analyses were conducted to examine the causal relationship between genetically predicted serum magnesium levels and CKD risk.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Multivariable cox regression analyses identified that hypomagnesemia was significantly associated with an increased risk of CKD, with a hazard ratio of 1.73 (95% CI: 1.14-2.61, p=0.010). Analyses based on single SNPs and SNP scores did not reveal direct effects on CKD risk. Mediation analyses demonstrated that 4 SNPs exerted significant indirect effects on CKD risk through serum magnesium levels. However, the proportion of the total effect mediated by magnesium was low and not statistically significant. MR analyses did not provide strong evidence for a significant causal relationship between genetically predicted magnesium levels and CKD risk.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Hypomagnesemia was significantly associated with an increased risk of long-term CKD. Genetic analysis suggests that serum magnesium levels may play an indirect role in CKD risk, but no clear causal relationship was found.<\/jats:p>\n <\/jats:sec>","DOI":"10.1093\/ckj\/sfaf254","type":"journal-article","created":{"date-parts":[[2025,8,12]],"date-time":"2025-08-12T21:36:53Z","timestamp":1755034613000},"source":"Crossref","is-referenced-by-count":0,"title":["Exploring the relationship between serum magnesium levels, genetic variants, and chronic kidney disease: a prospective study"],"prefix":"10.1093","author":[{"given":"Sisi","family":"Xie","sequence":"first","affiliation":[{"name":"Lausanne University Hospital and University of Lausanne Department of Medicine, Division of Medicine, , Lausanne ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Idris","family":"Guessous","sequence":"additional","affiliation":[{"name":"Primary care medicine service , Department of Primary Care Medicine, Geneva University Hospitals"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dela","family":"Golshayan","sequence":"additional","affiliation":[{"name":"Lausanne University Hospital and University of Lausanne Department of Medicine, Transplantation Center, , Lausanne ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6790-2285","authenticated-orcid":false,"given":"Aur\u00e9lien","family":"Thomas","sequence":"additional","affiliation":[{"name":"Faculty Unit of Toxicology, CURML, Faculty of Biology and Medicine, University of Lausanne , Lausanne ,","place":["Switzerland"]},{"name":"Unit of Forensic Toxicology and Chemistry, CURML, Lausanne and Geneva University Hospitals , Lausanne, Geneva ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julien","family":"Vaucher","sequence":"additional","affiliation":[{"name":"Lausanne University Hospital and University of Lausanne Department of Medicine, Division of Medicine, , Lausanne ,","place":["Switzerland"]},{"name":"Division of internal medicine, Fribourg hospital and university of Fribourg Department of internal medicine and specialties, , Fribourg ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4548-8500","authenticated-orcid":false,"given":"Pedro","family":"Marques-Vidal","sequence":"additional","affiliation":[{"name":"Lausanne University Hospital and University of Lausanne Department of Medicine, Division of Medicine, , Lausanne ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,8,8]]},"container-title":["Clinical Kidney Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/ckj\/advance-article-pdf\/doi\/10.1093\/ckj\/sfaf254\/63991511\/sfaf254.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ckj\/advance-article-pdf\/doi\/10.1093\/ckj\/sfaf254\/63991511\/sfaf254.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,12]],"date-time":"2025-08-12T21:36:53Z","timestamp":1755034613000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ckj\/advance-article\/doi\/10.1093\/ckj\/sfaf254\/8228472"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1093\/ckj\/sfaf254","relation":{},"ISSN":["2048-8505","2048-8513"],"issn-type":[{"value":"2048-8505","type":"print"},{"value":"2048-8513","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,8]]},"article-number":"sfaf254"}}
