RCV000468308 | SCV000541147 | uncertain significance | Peutz-Jeghers syndrome | 2024-07-26 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 425 of the STK11 protein (p.Arg425Pro). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with STK11-related conditions. ClinVar contains an entry for this variant (Variation ID: 403784). 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 STK11 protein function with a negative predictive value of 95%. 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. |
| Ambry Genetics | RCV002374735 | SCV002687922 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-08-05 | criteria provided, single submitter | clinical testing | The p.R425P variant (also known as c.1274G>C), located in coding exon 9 of the STK11 gene, results from a G to C substitution at nucleotide position 1274. The arginine at codon 425 is replaced by proline, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. 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. |
| Quest Diagnostics Nichols Institute San Juan Capistrano | RCV003477938 | SCV004221272 | uncertain significance | not provided | 2023-01-11 | criteria provided, single submitter | clinical testing | The variant has not been reported in the published literature. It also has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. |
