Q. A 35-year-old woman presents to her primary care physician with a six-month history of muscle cramps and tingling sensations in her fingers and toes. She also reports a history of short stature, round face, shortened 4th and 5th digits, subcutaneous calcifications, developmental delay, and a family history of similar symptoms. The patient's vital signs on presentation are blood pressure 120/80 mm Hg, pulse rate 80 beats/minute, and respiratory rate 16 breaths/minute. Further evaluation reveals low levels of calcium, high levels of parathyroid hormone, and high levels of phosphate in the patient's blood. What is the most likely diagnosis?
