MEN1 and parathyroid hyperplasia: Studies evaluating the miR profile in MEN1‐linked parathyroid hyperplasia found increased expression of miR‐24 predicted to bind mainly the 3‐UTR of MEN1 mRNA.(13, 14) In particular, MEN1‐related parathyroid tumors harboring the MEN1 loss of heterozygosity (LOH) at 11p13 (thus completely missing the expression of wild type MEN1 mRNA and menin protein) showed higher expression of miR‐24 compared with MEN1 PAs without LOH at 11q13 or somatic mutations of the MEN1 gene.
