Laboratory tests revealed a normochromic normocytic anemia (8 g/dL), serum calcium of 15.5 mg/dL (8.2–10.2), phosphate of 1.0 mg/dL (2.3–4.7), albumin of 3.9 mg/dL (3.5–5.0), parathyroid hormone (PTH) of 2000 pg/mL (18–50), alkaline phosphatase of 262 IU/L (50–120), and 25-hydroxyvitamin D of 18 ng/mL (30–70). This evidence concerns the gene PTH and anemia.
