    In the nuclear receptor of vitamin D (VDR) histidine 305 participates to the anchoring of the ligand. The VDR H305Q mutation was identified in a patient who exhibited the hereditary vitamin D-resistant rickets (HVDRR). We report the crystal structure of human VDR H305Q-ligand binding domain bound to 1alpha,25(OH)2D3 solved at 1.8A resolution. The protein adopts the active conformation of the wild-type liganded VDR. A local conformational flexibility at the mutation site weakens the hydrogen bond between the 25-OH with Gln305, thus explaining the lower affinity of the mutant proteins for calcitriol. The structure provides the basis for a rational approach to the design of more potent ligands for the treatment of HVDRR.
