NCI Definition: A malignant tumor arising from the epithelium of the gallbladder. It is usually associated with the presence of gallstones. Clinical symptoms are not specific and usually present late in the course. Morphologically, most gallbladder carcinomas are adenocarcinomas; squamous cell carcinomas, adenosquamous carcinomas, signet ring carcinomas, and undifferentiated carcinomas can also occur. [1]

Gallbladder carcinomas most frequently harbor alterations in TP53, SMAD4, CDKN2A, ARID1A, and CDKN2B [2].

Most Commonly Altered Genes in Gallbladder Carcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 c.142-c.212 Missense, TP53 c.1-c.137 Missense, and TP53 Missense are the most common alterations in gallbladder carcinoma [2].
