Summaries for Hypomagnesemia 1, Intestinal

NIH Rare Diseases : 54 Familial hypomagnesemia with secondary hypocalcemia is a disease characterized by very low magnesium levels in the blood. The disease begins during the first months of life with generalized and recurrent seizures which do not improve with usual treatment. Additional features include tetany (spasms of the hands and feet, cramps, spasm of the voice box (larynx), and overactive neurological reflexes), failure to thrive, restlessness, tremors, muscle spasms, and bluish skin around the mouth (perioral cyanosis). Abnormal heart rhythm (cardiac arrhythmia) may be observed. The low levels of magnesium result in low levels of parathyroid hormone (PTH) and in low levels of calcium in the bloods (hypocalcemia). It is caused by mutations in the TRPM6 gene. Inheritance is autosomal recessive. Untreated, the disease may be fatal or lead to severe neurologic damage. Treatment involves giving magnesium, usually in the vein (intravenously), followed by life-long high-dose oral magnesium.

MalaCards based summary : Hypomagnesemia 1, Intestinal, also known as intestinal hypomagnesemia with secondary hypocalcemia, is related to primary hypomagnesemia and hypomagnesemia 3, renal, and has symptoms including seizures and spasm. An important gene associated with Hypomagnesemia 1, Intestinal is TRPM6 (Transient Receptor Potential Cation Channel Subfamily M Member 6), and among its related pathways/superpathways are Tight junction and Cell adhesion molecules (CAMs). Affiliated tissues include kidney, skin and heart, and related phenotypes are seizures and tetany

Disease Ontology : 12 A hypomagnesemia characterized by very low serum magnesium levels due to defects in intestinal absorbtion and kidney excretion and secondary hypocalcemia that has material basis in homozygous or compound heterozygous mutations in the TRPM6 gene on chromosome 9q21.

Genetics Home Reference : 26 Hypomagnesemia with secondary hypocalcemia is an inherited condition caused by the body's inability to absorb and retain magnesium that is taken in through the diet. As a result, magnesium levels in the blood are severely low (hypomagnesemia).

OMIM : 58 Familial hypomagnesemia with secondary hypocalcemia is a rare autosomal recessive disorder characterized by very low serum magnesium levels. Hypocalcemia is a secondary consequence of parathyroid failure and parathyroid hormone resistance as a result of severe magnesium deficiency. The disease typically manifests during the first months of life with generalized convulsions or signs of increased neuromuscular excitability, such as muscle spasms or tetany. Untreated, the disease may be fatal or lead to severe neurologic damage. Treatment includes immediate administration of magnesium, usually intravenously, followed by life-long high-dose oral magnesium (review by Knoers, 2009). (602014)

UniProtKB/Swiss-Prot : 76 Hypomagnesemia 1: A disorder due to a primary defect in intestinal magnesium absorption. It is characterized by low levels of serum magnesium alongside with a normal renal magnesium secretion, secondary hypocalcemia and calcinocis. Affected individuals show neurologic symptoms of hypomagnesemic hypocalcemia, including seizures and muscle spasms, during infancy. Hypocalcemia is secondary to parathyroid failure resulting from magnesium deficiency. Untreated, the disorder may be fatal or may result in neurological damage.
