Overview

Primitive cancers have so-called hot-spot mutations in DICER1 that alter the function of DICER1, an enzyme that processes microRNA. Some of these cancers harbor a loss-of-function mutation in the other DICER1 allele, suggesting a new mutational mechanism of oncogenesis. Sex cord–stromal tumors and germ-cell tumors account for less than 10% of ovarian cancers. 1 Unlike epithelial ovarian cancers, both sex cord–stromal tumors and germ-cell tumors can also occur in the testicle; testicular germ-cell tumors are the most common cancer in boys and men of European descent between the ages of 15 and 34 years. 2 , 3 Other than a pathognomonic somatic mutation in FOXL2 in adult granulosa-cell tumors, 4 – 6 little is known about the pathogenesis of ovarian sex cord–stromal tumors and germ-cell tumors. Recently, germline mutations in the microRNA processing gene DICER1 have been reported in probands with pleuropulmonary blastoma or . . .
