Pedigree showing some of the features of a family with a deleterious MEN1 mutation across four generations, including transmission occurring through paternal lineage. The unaffected male proband is shown as having an affected sister (self-report of neck surgery confirmed upon review of medical records to be hyperparathyroidism diagnosed at age 18 y, parathyroidectomy, and pituitary adenoma), father (self-report of stomach cancer confirmed upon review of medical records to be gastrinoma diagnosed at age 45 y), and paternal grandmother (suspected hyperparathyroidism and/or pancreatic tumor).
