Increased levels of secondary hormones, such as gastrin (4 patients), vasoactive intestinal peptide (1 patient), serotonin (5 patients), insulin (6 patients, clinically significant in 1 only), human pancreatic polypeptide (2 patients), calcitonin (2 patients) and adrenocorticotropic hormone (2 patients), contributed to clinical symptoms leading to the diagnosis of an islet cell tumor before the onset of the full glucagonoma syndrome in 2 patients.

More recently, islet amyloid polypeptide or amylin, and adrenomedullin were isolated from human insulinoma and pheochromocytoma respectively, and revealed between 25 and 50% sequence homology with CGRP.

Indeed, modulation of adenylate cyclase activity following receptor activation has been reported for CGRP, amylin and adrenomedullin.

The cloning of various calcitonin and most recently of CGRP1 and adrenomedullin receptors was reported and revealed structural similarities but also significant differences to other members of the G protein-coupled receptors.

CGRP receptor belongs to the calcitonin receptor like receptor (CRLR) family of G-protein-coupled receptors and has been shown to require a single transmembrane domain protein called receptor activity modifying protein-1 (RAMP1) for its functional expression as well as activity.

After removal of the pancreatic tumor, clinical symptoms resolved and biochemical markers normalized (serum insulin, 14.9 microU/ml; C-peptide, 3.0 ng/ml; calcitonin, 2.9 pg/ml) confirming the causal relationship between insulinoma and markedly increased serum calcitonin levels.
