showed that in 57 patients with PHPT (including 11 parathyroid carcinomas and 46 parathyroid adenomas), the expression of long-chain non-coding RNA (lncRNA) scores and PVT1 expression levels were significantly higher in the parathyroid carcinoma subgroup than in the adenoma patients, and their elevation correlated with the severity of hypercalcaemia. The gene discussed is PVT1; the disease is adenoma.
