Genes affected
DICER1 (HGNC:17098): (dicer 1, ribonuclease III) This gene encodes a protein possessing an RNA helicase motif containing a DEXH box in its amino terminus and an RNA motif in the carboxy terminus. The encoded protein functions as a ribonuclease and is required by the RNA interference and small temporal RNA (stRNA) pathways to produce the active small RNA component that represses gene expression. This protein also acts as a strong antiviral agent with activity against RNA viruses, including the Zika and SARS-CoV-2 viruses. Alternative splicing results in multiple transcript variants.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 20, 2019 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in DICER1 are known to be pathogenic (PMID: 19556464, 21266384). This variant has been observed in an individual affected with pleuropulmonary blastoma (PMID: 26925222) and has also been observed to be de novo in an individual affected with DICER1 syndrome (PMID: 28960912). ClinVar contains an entry for this variant (Variation ID: 254337). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Cys1535Trpfs*3) in the DICER1 gene. It is expected to result in an absent or disrupted protein product. - |
