No pathogenic criterion marked as applied in the recorded assessment.
This variant exceeds the DICER1 BA1 threshold of >0.003 in a gnomAD subpopulation with >2,000 alleles tested and at least 5 variant alleles. In gnomAD v4.1, the African/African American subpopulation frequency is 0.118819 (8910/74988 alleles); gnomAD v2.1 similarly shows 0.121573 (3033/24948 alleles).
This variant exceeds the DICER1 BS1 threshold of >0.0003 in a gnomAD subpopulation with >2,000 alleles tested and at least 5 variant alleles. In gnomAD v4.1, the African/African American subpopulation frequency is 0.118819 (8910/74988 alleles), well above the threshold.
This variant is observed in many homozygous individuals in population databases lacking individual clinical information, meeting the DICER1 BS2 Supporting rule for 2 or more homozygous observations without clinical data. gnomAD v4.1 reports 594 homozygotes overall, and gnomAD v2.1 reports 195 homozygotes overall.

The DICER1 NM_177438.3:c.3033G>A (NP_803187.1:p.(Ala1011=)) variant has been reported in ClinVar with multiple benign submissions.
This variant is common in population databases, including gnomAD v4.1 at 0.62710% overall and 11.88190% in the African/African American subpopulation (8910/74988 alleles, 594 homozygotes overall), which exceeds the DICER1 BA1 threshold of 0.3% and BS1 threshold of 0.03%.
SpliceAI predicts no significant splice impact, with a maximum delta score of 0.01, arguing against an abnormal splicing effect for this synonymous change, although BP4/BP7 were not fully applied because concordant MaxEntScan evidence was not identified.
No criteria match.
BA1: frequency >0.003 in a gnomAD subpopulation with >2,000 alleles tested and at least 5 alleles present.
BS1: frequency >0.0003 in a gnomAD subpopulation with >2,000 alleles tested and at least 5 alleles present.
BS2_Supporting: 2+ observations of homozygosity in individuals lacking clinical information.
PM2_Supporting requires allele frequency <0.000005 across gnomAD with no more than one allele in any subpopulation.
PP3 requires agreement in splicing predictors predicting a splicing effect for synonymous/intronic/non-coding variants.
PS1 requires an established pathogenic comparator with the same amino-acid change and no relevant splicing difference.
PS2 uses DICER1 de novo point thresholds.
PS3 requires qualifying RNA or functional assay evidence under the DICER1 specification.
PP1 requires DICER1 segregation meiosis thresholds.
PP4 requires specific DICER1 tumor-testing findings.
BS3 for synonymous/intronic variants requires repeated RNA evidence showing no splicing impact.
BS4 requires phenotype-positive, genotype-negative relatives under the DICER1 specification.
BP2 requires qualifying trans or repeated cis/phase-unknown observations with pathogenic DICER1 variants.
BP4 for synonymous/intronic/non-coding variants requires concordance of MaxEntScan and SpliceAI predicting no splicing effect.
BP7 applies to silent variants only when BP4 is also met under the DICER1 specification.
DICER1 PVS1 applies to qualifying loss-of-function variants; this variant does not fit those classes.
PM1 is specified for putative missense variants in defined RNase IIIb hotspot/domain residues.
Not applicable in the DICER1 specification.
PM4 applies to in-frame indels under the DICER1 specification.
PM5 applies to qualifying missense variants with a pathogenic same-residue comparator.
