In comparison with patients without renal calcification, patients with calcifications had significant higher values for serum PTH levels (137.00 vs. 86.40 pg/mL, P = 0.001), 1.25(OH)2D (96.83 ± 20.00 vs. 62.36 ± 21.24 pg/mL, P = 0.005), and urinary calcium (160.00 vs. 116 mg/day, P = 0.037) and lower values for serum phosphate (3.13 ± 0.38 vs. 3.57 ± 0.59 mg/dL, P = 0.041) (Table 2). The gene discussed is PTH; the disease is calcification.
