NCI Definition: A renal cell carcinoma characterized by morphologic features that do not fit easily into one of the other well-defined categories of renal cell carcinoma. Examples of such features include mixtures of morphologic patterns, mucin production, and sarcomatoid morphology. [1]

Unclassified renal cell carcinomas most frequently harbor alterations in NF2, SETD2, TP53, BAP1, and CDKN2B [2].

Most Commonly Altered Genes in Unclassified Renal Cell Carcinoma

TP53 Mutation, NF2 Mutation, CDKN2B Loss, TP53 c.217-c.1178 Missense, and TP53 Missense are the most common alterations in unclassified renal cell carcinoma [2].
