In 2012, using a combination of whole transcriptome and whole exome sequencing analyses, Heravi-Moussavi et al. sequenced 14 non-epithelial ovarian tumors identifying closely clustered missense mutations in the region of DICER1 gene encoding the RNase IIIb domain in a total of four samples [35]. The gene discussed is DICER1; the disease is ovarian epithelial tumor.
