DLK1 is located in the DLK1/MEG3 imprinted locus on human chromosome 14q32.3 and MEG3, coding for a maternally imprinted long noncoding RNA with tumor suppressive function, was also found to be specifically silenced through methylation in NFPAs, but not in other hypophyseal adenoma types [13]. Here, MEG3 is linked to neoplasm.
