Familial hypomagnesemia with hypercalciuria and nephrocalcinosis in 2 sisters.
Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive tubular disorder characterized by excessive renal magnesium and calcium wasting, eventually, progressing to renal failure. It has been recently attributed to a mutation in the Claudin 16 (CLDN 16) gene of the Paracellin-1 (PCLN-1) tight junction protein. Herein, we report 2 sisters with FHHNC....
متن کاملIdentification of the first large deletion in the CLDN16 gene in a patient with FHHNC and late-onset of chronic kidney disease: case report
BACKGROUND Familial hypomagnesemia with hypercalciuria and nephrocalcinosis is a rare autosomal recessive renal disease characterized by tubular disorders at the thick ascending limb of Henle's loop. It is caused by mutations in the tight junction structural proteins claudin-16 or claudin-19, which are encoded by the CLDN16 and CLDN19 genes, respectively. Patients exhibit excessive wasting of c...
متن کاملNephrocalcinosis in siblings--familial hypomagnesemia, hypercalciuria with nephrocalcinosis (FHHNC syndrome).
Familial Hypomagnesemia, Hypercalciuria with Nephrocalcinosis is a rare autosomal recessive inherited disease associated with renal failure. Two girls born of consanguineous parentage aged 16 and 17 presented to us with renal failure, nephrocalcinosis and bone deformities. On evaluation they were found to have hypomagnesemia, hypercalciuria, increased fractional excretion of magnesium, hypocitr...
متن کاملAn Evidence-Based Approach to Clinical Cases
Hypomagnesemia is defined as a serum magnesium level less than 1.8 mg/dL (< 0.74 mmol/L). Hypomagnesemia may result from inadequate magnesium intake, increased gastrointestinal or renal losses, or redistribution from extracellular to intracellular space. Increased renal magnesium loss can result from genetic or acquired renal disorders. Most patients with hypomagnesemia are asymptomatic and sym...
متن کاملInherited hypercalciuric syndromes: Dent's disease (CLC-5) and familial hypomagnesemia with hypercalciuria (paracellin-1).
Dent's disease and familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) are inherited diseases in which hypercalciuria, nephrocalcinosis, and renal failure are prominent features. Dent's disease resembles a Fanconi syndrome, with impaired reabsorption in the proximal tubule; FHHNC, with urinary loss of magnesium and calcium, is associated with impaired cation transport in th...
