NCI Definition: A malignant neoplasm that originates in the neuroectoderm. The neuroectoderm constitutes the portion of the ectoderm of the early embryo that gives rise to the central and peripheral nervous systems and includes some glial cell precursors. [1]

Primitive neuroectodermal tumors most frequently harbor alterations in TP53, SQSTM1, SETBP1, CDKN2B, and XPO1 [2].

Most Commonly Altered Genes in Primitive Neuroectodermal Tumor

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