No Change....needed?: In fbhh, the problem lies in the parathyroid perception of ca concentration. The ca sensing receptor (casr) doesn't sense the ca level correctly, resulting in PTH being elevated and kidney resorption increasing. While ca-vit d increases abdominal absorption, it doesn't change the underlying error. Additionally, these patients do not get kidney stones/osteoporosis at an increased rate (asympt).
