NCI Definition: A benign or malignant neoplasm affecting the pituitary gland. The vast majority are adenomas arising from the anterior lobe of the pituitary gland. [1]

Pituitary gland neoplasms most frequently harbor alterations in GNAS, PRKDC, ARID1B, PTPRD, and FANCA [2].

Most Commonly Altered Genes in Pituitary Gland Neoplasm

GNAS Mutation, PRKDC Mutation, ARID1B Mutation, FANCA Mutation, and KMT2D Mutation are the most common alterations in pituitary gland neoplasm [2].
