Familial Vitamin D-resistant rickets with hypophosphatemia presents the challenge of apparently simple genetics but multi-organ sites of expression of the disorder. With very rare exceptions its inheritance is consistent with a single-dose effect in the X-linked gene ("sex-linked dominance"), and, when hypophosphatemia is used as the indicator of its presence, the degree of expressivity or penetrance is virtually complete. How, then, does one account in a unifying way for the findings of [1] decreased net renal tubular reabsorption of phosphate (which presumably is the explanation for the hypophosphatemia), [2] decreased intestinal reabsorption of calcium, [3] the bony abnormalities consisting not
