<unk>  <unk>  is a rare hereditary disease in which excessive loss of phosphate in the urine leads to poorly formed bones<unk> , bone pain, and tooth abscesses.<unk>  is caused by a mutation in the fibroblast growth factor 23 (FGF23).<unk>  affects men and women equally; symptoms may become apparent at any point from childhood through early adulthood. Blood tests reveal low levels of phosphate <unk>  and inappropriately normal levels of vitamin D. Occasionally,<unk>  may improve over time as urine losses of phosphate partially correct.<unk>  may be lumped in with X-linked<unk>  under general terms such as<unk><unk> .<unk><unk>  are associated with at least nine other genetic mutations. Clinical management of<unk><unk>  may differ depending on the specific mutations associated with an individual case, but treatments are aimed at raising phosphate levels to promote normal bone formation.
