title: [Clinical importance of disorders of vitamin D metabolism].
abstract: Some aspects of disordered vitamin D metabolism are reviewed. The causes and consequences of diminished blood levels of 25-OH-D3 are discussed. The role of 1,25(OH)2D3 in calcium and phosphorus homeostasis is presented and the diseases associated with alterations of this hormone are described.
