| Invitae | RCV001037992 | SCV001201432 | uncertain significance | DICER1-related tumor predisposition | 2022-12-03 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 836789). 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). This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 259 of the DICER1 protein (p.Pro259Arg). |
| Ambry Genetics | RCV002409375 | SCV002672206 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-03-30 | criteria provided, single submitter | clinical testing | The p.P259R variant (also known as c.776C>G), located in coding exon 6 of the DICER1 gene, results from a C to G substitution at nucleotide position 776. The proline at codon 259 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
