MEN1 and multiple endocrine neoplasia type 1: For example, “Epstein-Barr” probably refers to either to “Epstein-Barr virus” or “Epstein-Barr infection” and “Multiple Endocrine Neoplasia Type 1 (MEN1)” refers to “MEN1 syndrome” or “MEN1 gene.” We recommend preferring the precise and complete scientific term wherever possible.
