Isolated dominant hypomagnesemia (IDH) is an autosomal dominant disorder of magnesium wastage. The mild hypomagnesemia occurs without other electrolyte abnormalities. A mutation in the FXYD2 gene is responsible for this disorder.
An autosomal dominant magnesium wasting disorder has been first described by Geven in 1987.[Error: Macro 'ref' doesn't exist]
Hypomagnesemia is the single symptom of isolated hypomagnesemia (IDH). No other solute disturbances are seen.
