Familial hypomagnesemia, hypercalciuria with nephrocalcinosis syndrome: report of a case.
Summary of "Familial hypomagnesemia, hypercalciuria with nephrocalcinosis syndrome: report of a case."
Familial hypomagnesemia and hypercalciuria with nephrocalcinosis is a rare autosomal recessive disease characterized by renal calcium and magnesium wasting, evolving in the progressive decrease of renal function, eventually requiring kidney transplant. Clinical findings include urinary infection, polyuria, polydipsia, cramps, tremors, convulsions, among others; these, asociated to ocular and/or auditive abnormalities. We present a 4 year-old female with the syndrome, which was manifested by typical signs and symptoms in daily practice: fever, abdominal pain, polyuria and polydipsia. These symptoms may defer the diagnosis of the syndrome.

Medical and Biotech [MESH] Definitions
An inherited renal disorder characterized by defective NaCl reabsorption in the convoluted DISTAL KIDNEY TUBULE leading to HYPOKALEMIA. In contrast with BARTTER SYNDROME, Gitelman syndrome includes hypomagnesemia and normocalcemic hypocalciuria, and is caused by mutations in the thiazide-sensitive SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.
X-linked recessive NEPHROLITHIASIS characterized by HYPERCALCIURIA; HYPOPHOSPHATEMIA; NEPHROCALCINOSIS; and PROTEINURIA. It is associated with mutations in the voltage-gated chloride channel, CLC-5 (Dent Disease I). Another group of mutations associated with this disease is in phosphatidylinositol 4,5-bisphosphate-5-phosphatase gene.
A condition characterized by calcification of the renal tissue itself. It is usually seen in distal RENAL TUBULAR ACIDOSIS with calcium deposition in the DISTAL KIDNEY TUBULES and the surrounding interstitium. Nephrocalcinosis causes RENAL INSUFFICIENCY.
Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.
A hereditary or acquired form of generalized dysfunction of the PROXIMAL KIDNEY TUBULE without primary involvement of the KIDNEY GLOMERULUS. It is usually characterized by the tubular wasting of nutrients and salts (GLUCOSE; AMINO ACIDS; PHOSPHATES; and BICARBONATES) resulting in HYPOKALEMIA; ACIDOSIS; HYPERCALCIURIA; and PROTEINURIA.
