Leucine-induced hypoglycemia (LIH)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionRare cause of hypoglycemia and is described as a condition in which symptomatic hypoglycemia is provoked by high protein feedings. Hypoglycemia is also elicited by administration of oral or intravenous infusions of a single amino acid, leucine.
