In addition to abovementioned genes, many genes that are rarely described in CKD progression were found differentially expressed in the rapid versus slow groups at T2 (e.g., LOX, PAMR1, CDCA8, C1QTNF6, FNDC1, CCDC80, MFSD7, FMO2, SI, SLC26A4). This evidence concerns the gene FNDC1 and chronic kidney disease.
