The recorded framework is ClinGen DICER1 VCEP v1.4.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
Population frequency exceeds the DICER1 BA1 threshold of >0.003 in a qualifying gnomAD subpopulation. In gnomAD v4.1, the African/African American subpopulation frequency is 0.11919 (8940/75006 alleles), which is far above the 0.003 threshold and includes far more than 5 alleles with >2000 alleles tested.
Population frequency exceeds the DICER1 BS1 threshold of >0.0003 in a qualifying gnomAD subpopulation. In gnomAD v4.1, the African/African American subpopulation frequency is 0.11919 (8940/75006 alleles), which is far above the 0.0003 threshold.
This variant is observed in homozygous state in population datasets lacking detailed clinical information, which supports BS2 at the supporting level under the DICER1 specification. gnomAD v4.1 reports 596 homozygotes, gnomAD v2.1 reports 195 homozygotes, and gnomAD-Canada reports 11 homozygotes.
ClinGen DICER1 and miRNA-Processing Gene Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for DICER1 Version 1.4.0 v1.4.0 point-based framework: BA1 stand-alone benign (-8) + BS1 strong (-4) + BS2 supporting (-1) = -13 points, which maps to Benign.

The DICER1 c.4680G>A (p.Ala1560=) variant has been reported in ClinVar with benign classifications from multiple clinical laboratories.
This variant is common in population databases, including gnomAD v4.1 with total allele frequency 0.00631 and African/African American allele frequency 0.11919, which is well above the DICER1 BA1 threshold of 0.003; gnomAD-Canada also shows allele frequency 0.00863 with 11 homozygotes.
Computational data do not support a splice-disrupting effect, with SpliceAI max delta score 0.01, and the REVEL score is 0.07.
No criteria match.
BA1 Stand Alone: frequency >0.003 in a qualifying gnomAD subpopulation.
BS1 Strong: frequency >0.0003 in a qualifying gnomAD subpopulation.
BS2 Supporting: 2+ observations of homozygosity in individuals lacking clinical information.
Requires a pathogenic comparator with the same amino acid change and no worse splicing impact.
Requires allele frequency <0.000005 with no more than one allele in any subpopulation.
Requires qualifying damaging computational evidence under the DICER1 specification.
Requires de novo points under the DICER1 specification.
Requires RNA or validated functional assay evidence showing a damaging effect.
Requires informative segregation across meioses under the DICER1 specification.
Requires qualifying tumor second-hit evidence under the DICER1 specification.
Requires RNA or qualifying benign functional evidence under the DICER1 specification.
Requires genotype-negative phenotype-positive relatives under the DICER1 specification.
Requires qualifying trans or repeated cis/unknown-phase observations under the DICER1 specification.
For synonymous variants, BP4 requires concordance of MaxEntScan and SpliceAI showing no splicing effect.
BP7 applies to silent variants only if BP4 is met and conservation does not argue against benignity.
