DICER1 (Endoribonuclease Dicer) variants and mutations

DICER1 (also known as Endoribonuclease Dicer) is a human protein-coding gene encoding an endoribonuclease Dicer protein. It cleaves precursor microRNAs into mature regulatory RNAs that guide post-transcriptional gene silencing. Germline pathogenic variants cause DICER1 tumor-predisposition syndrome, with increased risk of several rare childhood and young-adult tumors. This analysis covers 5,067 DICER1 variants and mutations. Of these, 53% have computational variant effect predictions. Disease context includes DICER1-related tumor predisposition, pleuropulmonary blastoma, and Familial multinodular goiter. Example DICER1 variants include M1?, K2N, and K2R.
