The term 'X-linked hypercalciuric nephrolithiasis' comprises several related forms of hereditary renal tubular disorders caused by mutations in the CLCN5 gene, including Dent disease, X-linked recessive nephrolithiasis (310468), X-linked recessive hypophosphatemic rickets (300554), and low molecular weight proteinuria (308990). Although these disorders are allelic and are all characterized by progressive proximal renal tubulopathy with hypercalciuria, low molecular weight proteinuria, and nephrocalcinosis, they vary in degree of severity and were originally reported as separate disorders. Some have considered these disorders as phenotypic variants of a single disease, referred to as the 'Dent disease complex' (Scheinman, 1998; Gambaro et al., 2004). Scheinman et al. (1999) provided a comprehensive review of genetic disorders of renal electrolyte transport.

Researchers have described two forms of Dent disease, which are distinguished by their genetic cause and pattern of signs and symptoms. Both forms of Dent disease (type 1 and type 2) are characterized by the features described above, but Dent disease 2 can also be associated with abnormalities unrelated to kidney function. These additional signs and symptoms include mild intellectual disability, weak muscle tone (hypotonia), and clouding of the lens of the eyes (cataract) that is described as subclinical because it does not impair vision. Some researchers consider Dent disease 2 to be a mild variant of a similar disorder called Lowe syndrome.

Some people with Dent disease develop rickets, a bone disorder that results when the levels of vitamin D and certain minerals (including calcium) in the blood become too low. Rickets can be associated with weakening and softening of the bones, bone pain, bowed legs, and difficulty walking.

The most frequent sign of Dent disease is the presence of an abnormally large amount of proteins in the urine (tubular proteinuria). Other common signs of the disorder include excess calcium in the urine (hypercalciuria), calcium deposits in the kidneys (nephrocalcinosis), and kidney stones (nephrolithiasis). Kidney stones can cause abdominal pain and blood in the urine (hematuria). In most affected males, progressive kidney problems lead to end-stage renal disease (ESRD) in early to mid-adulthood. ESRD is a life-threatening failure of kidney function that occurs when the kidneys are no longer able to filter fluids and waste products from the body effectively.

Dent disease is a chronic kidney disorder that occurs almost exclusively in males. In affected individuals, kidney problems result from damage to structures called proximal tubules. Signs and symptoms of this condition appear in early childhood and worsen over time.  https://medlineplus.gov/genetics/condition/dent-disease
