GLIS2-AS1 and parathyroid gland carcinoma: Zhang et al. (2019) observed that six CDC73-mutant parathyroid carcinoma samples showed a significantly higher expression of PVT1 (plasmacytoma variant translocation 1) and lower expression of GLIS2-AS1 (GLIS2 antisense RNA 1) compared to parathyroid carcinoma samples without CDC73 mutation, suggesting an association of changes in lncRNAs with modification of the CDC73 gene [52].
