The differential-diagnosis of Fanconi syndrome itself is broad and includes (non-exhaustively) mitochondrial respiratory chain diseases, metal intoxications, Wilson’s disease, cystinosis, multiple myeloma [especially when involving light chains (34)], Sjögren’s disease, medications like ifosfamide or tenofovir, genetics forms of renal tubular acidose, Dent’s disease and Lowe’s oculocerebrorenal syndrome (from OCRL1 or CLCN5 mutations). This evidence concerns the gene OCRL and Dent disease.
