Hyperparathyroidism-jaw Tumor Syndrome Confirmed by Preoperative Genetic Testing

抄録

We herein report the case of a young woman who was diagnosed with primary hyperparathyroidism and in whom genetic testing confirmed a diagnosis of hyperparathyroidism-jaw tumor syndrome. Familial hyperparathyroidism was suspected based on the patient's young age at the onset of the disease. Thus, genetic testing was performed. It showed a germline mutation in the HRPT2/CDC73 gene and confirmed the diagnosis of hyperparathyroidism-jaw tumor syndrome. Total parathyroidectomy was performed to prevent recurrence. In patients with early-onset hyperparathyroidism, genetic testing should be considered to facilitate the selection of a proper surgical procedure based on the consideration of future life expectancy.
