NCI Definition: A germ cell tumor arising in an anatomic site other than the testis or ovary (e.g., central nervous system, lung, mediastinum, and retroperitoneum). [1]

Extragonadal germ cell tumors most frequently harbor alterations in KRAS, CDKN1B, TP53, CCND2, and H3F3C [2].

Most Commonly Altered Genes in Extragonadal Germ Cell Tumor

CDKN1B Amplification, KRAS Amplification, H3F3C Amplification, CCND2 Amplification, and TP53 c.217-c.1178 Missense are the most common alterations in extragonadal germ cell tumor [2].
