NCI Definition: An intraventricular papillary neoplasm that originates from the choroid plexus epithelium. It includes the choroid plexus papilloma, atypical choroid plexus papilloma, and choroid plexus carcinoma. [1]

Choroid plexus neoplasms most frequently harbor alterations in TP53, IDH1, FGFR1, CIC, and ZFHX3 [2].

Most Commonly Altered Genes in Choroid Plexus Neoplasm

TP53 c.217-c.1178 Missense, TP53 Mutation, TP53 Missense, IDH1 Mutation, and TP53 Exon 8 Mutation are the most common alterations in choroid plexus neoplasm [2].
