Recurrent Somatic DICER1 Mutations in Nonepithelial Ovarian Cancers
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 g...

Summary: | 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.

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.

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 . . . |
