Idiopathic infantile hypercalcemia is autosomal recessive disorder that is characterized by severe hypercalcemia, failure to thrive, vomiting, dehydration, and nephrocalcinosis. It has been reported that mutations in the vitamin D-metabolizing enzyme CYP24A1 cause this disease. The presence of CYP24A1 mutations explains the increased sensitivity to vitamin D in patients with idiopathic infantile hypercalcemia.
