Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 3P and 1B. PM2PP2BP4
The NM_177438.3(DICER1):c.4226C>A(p.Ala1409Glu) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,457,926 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 Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A1409G) has been classified as Uncertain significance.

DICER1-related tumor predisposition Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 24, 2022 | This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 1409 of the DICER1 protein (p.Ala1409Glu). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 573102). This variant has not been reported in the literature in individuals affected with DICER1-related conditions. This variant is not present in population databases (gnomAD no frequency). - |
