Brachydactyly in Pseudopseudohypoparathyroidism

A 26-year-old woman was seen for a longstanding mild elevation of parathyroid hormone (PTH), with otherwise normal serum mineral levels. Repeat testing confirmed elevated PTH 75 pg/mL (15 to 65 pg/mL) with normal calcium 9.1 mg/dL (8.6 to 10.0 mg/dL), phosphorus 3.7 mg/dL (2.5 to 4.5 mg/dL), and creatinine 0.67 mg/dL (0.59 to 1.04 mg/dL). The results of 24-hour urine calcium excretion, thyroid stimulating hormone, and free thyroxine tests were normal. Total 25-hydroxy-vitamin D level was 18 ng/mL, indicating mild deficiency.
