Associated Genetic Biomarkers


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 MYCN, ALK, ATRX, RPTOR, and CD79B [2].

Most Commonly Altered Genes in Primitive Neuroectodermal Tumor

MYCN Amplification, ALK Mutation, ALK Missense, ATRX Mutation, and SOX9 Amplification are the most common alterations in primitive neuroectodermal tumor [2].
