In addition to the heritability studies, data from participants of the SKIPOGH and/or CoLaus cohorts were included in GWAS which identified new loci for kidney function and CKD [70], uromodulin production and excretion [29, 40], albuminuria [58, 59], serum urate levels [61], magnesium and calcium homeostasis [6, 7], and osmoregulation [3]. This evidence concerns the gene UMOD and chronic kidney disease.
