A 7-year-old boy with severe rickets that by clinical analysis was diagnosed as affected
by type II vitamin D-dependent rickets, was evaluated for mutations in the vitamin
D receptor gene (VDR). The molecular analysis showed a homozygous state for a novel
missense mutation (C84R) in a highly conserved nucleotide in the second Zn finger
of the DNA binding domain.
