Dent Disease 2

Dent disease is characterized by renal Fanconi syndrome with low molecular weight proteinuria, hypercalciuria, nephrolithiasis (kidney stones), nephrocalcinosis (calcification of renal tissue) and progressive renal failure. Mutations in the OCRL gene also cause a form of Dent disease, known as Dent disease 2 (OMIM 300555). Although the most common cause of Dent disease is mutations in the CLCN5 gene, approximately 16-23% of Dent disease cases are due to mutations in the OCRL gene. Dent disease is a rare X-linked disorder characterized by renal Fanconi syndrome, without the cataracts and neurologic deficits that occur in Lowe syndrome.
