The genetic background of acromegaly

Acromegaly is caused by excess growth hormone (GH) secreted from the pituitary gland most often due to a somatotropinoma. While somatotropinomas are monoclonal tumors that occur sporadically in the vast majority of the patients, acromegaly can also be part of a familial disease. No exact data are available in what percentage of unselected acromegaly patients have a congenital (germline or mosaic) cause of their disease. We know, however, that almost 50% of childhood-onset cases leading to gigantism have a now identifiable genetic background [1, 2].

Tumor development is a complex multistep process influenced by genetic, epigenetic and environmental factors as well as by the tumor microenvironment. In this brief overview, we concentrate on the genetic basis of sporadic and familial acromegaly while refer to an excellent review regarding other molecular mechanisms [3].

Acromegaly can be part of a syndromic disease occurring concomitantly with other endocrine tumors, such as in MEN1, MEN4, Carney complex, McCune-Albright and SDHx-related pituitary adenomas (Table 1) or presents as part of familiar isolated pituitary adenoma (FIPA) in aryl hydrocarbon receptor interacting protein (AIP) or GPR101 (G-protein coupled receptor 101) mutation p

Acromegaly and gigantism

Introduction

Overview

Acromegaly is a disease characterized by the gradual enlargement of the peaked (acral) parts of the body, including the nose, lips, tongue, lower jaw, hands, and feet and by hyperplastic alterations in the entire osseous system. Gigantism occurs before epiphyseal closure. AIP gene mutations (AIPmut) often predispose to familial isolated pituitary adenomas with clinical features that may negatively impact treatment efficacy. The clinical picture of acromegaly is influenced by many factors, including the levels of growth hormone and insulin-like growth factor, age, tumor size, and delay in diagnosis. Surgical excision of the adenoma by transnasal transsphenoidal approach or by endoscopic endonasal transsphenoidal surgery is recommended. Pegvisomant is a medical therapy that blocks growth hormone action at peripheral receptors, normalizes insulin-like growth factor-1 levels, reduces signs and symptoms, and corrects metabolic defects.

Key points

• Acromegaly is characterized by the gradual enlargement of the acral parts of the body, with hyperplastic alterations in the entire osseous system due to growth hormone excess after epiphyseal closure.

• Gigantism occurs with growth hormone excess before epiphyseal closure

Introduction

Acromegaly is caused by marsh circulating levels of increase hormone (GH) and insulin-like growth consequence 1 (IGF1), which typically result overrun a GH-secreting pituitary adenoma¹.
