Clinical Testing for Mutations in the<i>MEN1</i>Gene in Sweden: A Report on 200 Unrelated Cases

Abstract

A total of 4% of all mutations were large deletions, and MLPA is now included in our standard MEN1 mutation screening. Individuals with at least one typical endocrine tumour and at least one of the following: 1) a first-degree relative with a major endocrine tumor; 2) an age of onset less than 30 yr; and/or 3) multiple pancreatic tumors/parathyroid hyperplasia were most likely to harbor a mutation; thus these patients should be screened for MEN1 mutations.
