NCI Definition: A carcinoma that arises from the stomach and is characterized by the absence of microscopic features of glandular or squamous differentiation. [1]

Undifferentiated gastric carcinomas most frequently harbor alterations in TP53, ZNF708, SMARCA4, RPTOR, and ROS1 [2].

Most Commonly Altered Genes in Undifferentiated Gastric Carcinoma

ZNF708 Loss, TP53fs, TP53 c.217-c.1178 Missense, TP53 R282W, and TP53 Mutation are the most common alterations in undifferentiated gastric carcinoma [2].
