Abstract

Objectives: To present a case of a new pathogenic variant of DICER1.

Case presentation: 13-year-old female with non-toxic multinodular goiter and ovarian Sertoli-Leydig cell tumor, in whom a pineal parenchymal tumor of intermediate differentiation was diagnosed. Next-generation sequencing revealed a new germline mutation in the DICER1 gene (exon 16, c2488del [pGlu830Serfs*2] in heterozygosis), establishing the diagnosis of DICER1 syndrome.

Conclusions: Mutations in the DICER1 gene cause genetic predisposition to a wide spectrum of benign or malignant tumors from childhood to adulthood.

Keywords: DICER1 syndrome; multinodular goiter; ovarian Sertoli–Leydig cell tumor; pineal parenchymal tumor of intermediate differentiation.
