Evidence submitted by expert panel

DICER1 and miRNA-Processing Gene VCEP

The NM_177438.3:c.5422A>G variant in DICER1 is a missense variant predicted to cause substitution of methionine by valine at amino acid 1808 (p.Met1808Val). This variant has an allele frequency of 0.0000008475 (1/1614140 alleles) across gnomAD v4.1.0 with no more than one allele in any subpopulation, which is lower than the ClinGen DICER1 VCEP threshold (<0.000005) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). The computational predictor REVEL gives a score of 0.656, which is neither above nor below the thresholds predicting a damaging or benign impact on DICER1 function (PP3 and BP4 not met). This variant resides within the RNase IIIb mutational hotspot domain with critical functionality as defined by the ClinGen DICER1 VCEP (PM1_Supporting; PMID: 31342592). In summary, this variant meets the criteria to be classified as Uncertain Significance for DICER1-related tumor predisposition based on the ACMG/AMP criteria applied, as specified by the ClinGen DICER1 VCEP: PM1_Supporting, PM2_Supporting. (Bayesian Points: 2; VCEP specifications version 1.3.0; 08/27/2024)

PM1_Supporting

This variant resides within the RNase IIIb mutational hotspot domain with critical functionality as defined by the ClinGen DICER1 VCEP (PM1_Supporting; PMID: 31342592).

PM2_Supporting

This variant has an allele frequency of 0.0000008475 (1/1614140 alleles) across gnomAD v4.1.0 with no more than one allele in any subpopulation, which is lower than the ClinGen DICER1 VCEP threshold (<0.000005) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting).
