Dent's disease (X-linked nephrolithiasis) is associated with mutations in the CLCN5 chloride channel gene, and low molecular weight (LMW) proteinuria was universally observed in affected males.
Genetic population studies tested the association of common allelic CASR variants with serum and urine calcium levels, kidney stone disease, primary hyperparathyroidism and bone mineral density.
Sixty percent of women with the CLC-5 deletion-insertion had nephrolithiasis, although calcium excretion before and after oral calcium challenge was similar to that in unaffected females.
We identify sequence variants associating with kidney stones at ALPL (rs1256328[T], odds ratio (OR)=1.21, P=5.8 × 10(-10)) and a suggestive association at CASR (rs7627468[A], OR=1.16, P=2.0 × 10(-8)).
Dent's disease, which is a renal tubular disorder characterized by low molecular weight proteinuria, hypercalciuria and nephrolithiasis, is associated with inactivating mutations of the X-linked chloride channel, CLC-5.
Characterization of novel promoter and enhancer elements of the mouse homologue of the Dent disease gene, CLCN5, implicated in X-linked hereditary nephrolithiasis.
Mutations in the CLCN5 gene have been demonstrated in three disorders of hypercalciuric nephrolithiasis, i.e., Dent's disease, X-linked recessive nephrolithiasis, and X-linked recessive hypophosphatemic rickets.
This study shows that genetic variants of the CaR gene are not associated with idiopathic hypercalciuria and calcium nephrolithiasis in this population of French Canadians.
Dent's disease, an X-linked disorder characterized by low molecular weight proteinuria, hypercalciuria, and nephrolithiasis, is due to mutations of the chloride/proton antiporter, CLC-5; ADHH is associated with activating mutations of the calcium-sensing receptor, which is a G protein-coupled receptor; hypophosphatemic hypercalciuric nephrolithiasis associated with rickets is due to mutations in the type 2c sodium-phosphate cotransporter (NPT2c); and familial hypomagnesemia with hypercalciuria is due to mutations of paracellin-1, which is a member of the claudin family of membrane proteins that form the intercellular tight junction barrier in a variety of epithelia.
In order to assess the eventual role of VDR gene start codon polymorphisms in stone production, we analyzed the genotype-phenotype association in a group of patients with calcium kidney stones.
Two SNPs in CaSR were genotyped using the TaqMan assay.We found that subjects carrying the G allele of rs6776158 (AG and GG) had significantly higher risk of nephrolithiasis compared to the AA genotype (P = .015 and .009, respectively).Our results indicate that rs6776158 polymorphism that might elevate the risk of nephrolithiasis in the Chinese population.
This study aimed to evaluate the association between genetic defects in vitamin D receptor (VDR), calcium sensing receptor (CaSR) and claudin 14 (CLDN14) genes and kidney stone disease in patients from eastern India.
Dent's disease, an X-linked disorder characterized by low molecular weight proteinuria, hypercalciuria, and nephrolithiasis, is due to mutations of the chloride/proton antiporter, CLC-5; ADHH is associated with activating mutations of the calcium-sensing receptor, which is a G protein-coupled receptor; hypophosphatemic hypercalciuric nephrolithiasis associated with rickets is due to mutations in the type 2c sodium-phosphate cotransporter (NPT2c); and familial hypomagnesemia with hypercalciuria is due to mutations of paracellin-1, which is a member of the claudin family of membrane proteins that form the intercellular tight junction barrier in a variety of epithelia.
Dent's disease (X-linked nephrolithiasis) is a proximal tubulopathy that has been consistently associated with inactivating mutations in the CLCN5 gene encoding the ClC-5 chloride channel expressed in tubular epithelial cells.
