Pathogenic variants in the CLCN5 gene encoding the chloride-hydrogen exchanger ClC-5 cause Dent’s disease type 1, a genetic disorder of the endolysosomal pathway in the proximal tubules of the kidneys. A hallmark of this disease is the downregulation of the protein uptake receptor consisting of megalin, cubilin and amnionless, causing low-molecular-weight proteinuria. Why these receptors are downregulated is not fully understood.
