Definition / general

Discovered on GIST 1
Primarily used in the diagnosis of gastrointestinal stromal tumor (GIST)

Essential features

Monoclonal (SP31, K9, DOG1.1) and polyclonal antibodies (Cancer Control 2015;22:498)
Most sensitive and specific marker for GIST

Terminology

Discovered on GIST 1 (Adv Anat Pathol 2017;24:336)
TMEM16A (Adv Anat Pathol 2017;24:336)
ANO1 (Adv Anat Pathol 2010;17:222)

Pathophysiology

Encoded by a locus at chromosome 11q13 and has 3 known splice variants (Am J Surg Pathol 2009;33:1401, Adv Anat Pathol 2010;17:222)
Transmembrane protein that encodes the chloride channel protein anoctamin 1 (Cancer Control 2015;22:498, Am J Dermatopathol 2017;39:896, Adv Anat Pathol 2017;24:336)
Present in many sites, such as the luminal surface of the gastric body and antral mucosa, salivary glands, pancreatic acini, intrahepatic bile ducts, gallbladder glandular elements, as well as breast and prostatic myoepithelial / basal cells (Am J Dermatopathol 2017;39:896)
In the interstitial cell of Cajal, found to contribute to the generation of pacemaker electrical activity that is important for the physiologic motility of the gastrointestinal tract (Adv Anat Pathol 2010;17:222)
DOG1 does not appear to bear mutations in its protein coding sequence in GIST (Adv Anat Pathol 2017;24:336, Int J Clin Exp Pathol 2015;8:5721)
Biologic significance of increased DOG1 expression in tumors is not entirely known (Adv Anat Pathol 2010;17:222)
