Submissions by phenotype
DICER1-related tumor predisposition Uncertain:1
This sequence change replaces proline with histidine at codon 1471 of the DICER1 protein (p.Pro1471His). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and histidine. This variant is not present in population databases (ExAC 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: 824875). 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. 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
The p.P1471H variant (also known as c.4412C>A), located in coding exon 22 of the DICER1 gene, results from a C to A substitution at nucleotide position 4412. The proline at codon 1471 is replaced by histidine, an amino acid with similar properties. This amino acid position is not 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. -
