24,25-dihydroxyvitamin D: a new biomarker in non-parathyroid hypercalcemia diagnosis
The 24,25-dihydroxyvitamin D [24,25(OH)2D] is a catabolite of 25-hydroxyvitamin D [25(OH)D]. This transformation is performed by 1,25-hydroxyvitamin D 24-hydroxylase (or 24-hydroxylase, encoded by the CYP24A1 gene). Mutations in CYP24A1 can lead to severe diseases such as idiopathic infantile hypercalcemia (IIH). Explorations of hypercalcemia with suppressed parathyroid hormone levels and normal or high phosphatemia should now […]
