Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 1P and 5B. PP2BP4BS2
The NM_177438.3(DICER1):c.2854A>T(p.Thr952Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000616 in 1,461,818 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 nucleotide change resulting in same amino acid change has been previously reported as Uncertain significancein ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T952A) has been classified as Uncertain significance.

DICER1-related tumor predisposition Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 19, 2022 | This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 952 of the DICER1 protein (p.Thr952Ser). This variant is not present in population databases (gnomAD no frequency). 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: 483455). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DICER1 protein function. 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 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 19, 2022 | The p.T952S variant (also known as c.2854A>T), located in coding exon 17 of the DICER1 gene, results from an A to T substitution at nucleotide position 2854. The threonine at codon 952 is replaced by serine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
