Other limitations of the study include the following: key parameters of calcium‐phosphorus homeostasis (1,25(OH)2D, fibroblast growth factor-23, ionized calcium, magnesium) were not taken into account; a single measure of PTH is not optimal due to biologic variation especially in this population with suboptimal calcium intake; and the participants were not screened for other abnormalities (such as elevated serum transaminase, hyperglycemia, clotting factor, low BMD, etc). The gene discussed is PTH; the disease is Hyperglycemia.
