Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 1P and 2B. PP2BP4_Moderate
The NM_177438.3(DICER1):c.1157A>G(p.Lys386Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,614,068 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict 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. K386K) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Aug 04, 2022 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 05, 2022 | The p.K386R variant (also known as c.1157A>G), located in coding exon 7 of the DICER1 gene, results from an A to G substitution at nucleotide position 1157. The lysine at codon 386 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is well 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. - |
