[Familial form of idiopathic hypercalciuria with nanism, bone and renal involvement in children].

A brother and a sister are reported, demonstrating the severe form of childhood idiopathic hypercalciuria associated with dwarfism, renal defects and bone lesions (rickets and osteoporosis). The family are Israeli Beduins from a small village with a highly inbred population. The parents who are first cousins, and the remaining 6 siblings are not affected. This suggests an autosomal recessive form of transmission for the trait.
