Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP6
The NM_177438.3(DICER1):c.1353A>G(p.Arg451=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,336 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R451R) has been classified as Likely benign.

Submissions by phenotype
DICER1-related tumor predisposition Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 13, 2023 | This sequence change affects codon 451 of the DICER1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the DICER1 protein. This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with DICER1-related conditions. ClinVar contains an entry for this variant (Variation ID: 412195). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 03, 2019 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
