Preferred Label : Dent disease 1;

CISMeF acronym : NPHL2;

Description : 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. - Genetic Heterogeneity of Dent Disease See also Dent disease-2 (300555), which is caused by mutation in the;
