Prolactinoma



Is a prolactinoma a genetic condition?

Most prolactinomas are thought to develop by chance without any known association to a genetic condition.[1]  However, up to 2.6% of individuals with a prolactinoma and no other symptoms may have a mutation in the MEN1 gene, which causes a genetic condition known as multiple endocrine neoplasia type 1 (MEN1).  The chance of a prolactinoma being associated with MEN1 increases if the tumor is large or affects surrounding tissues (is invasive), or if the individual develops multiple tumors, especially in other glands such as the parathyroids or pancreas.[1]  Prolactinomas have also been associated with another, very rare genetic condition called AIP-Related Familial Isolated Pituitary Adenomas, caused by mutations in the AIP gene; only 50 families with this condition have been described in the medical literature.[2][3]
