RCV003039024 | SCV003332488 | uncertain significance | Peutz-Jeghers syndrome | 2022-11-23 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 226 of the STK11 protein (p.Asn226Ser). 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on STK11 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. |
| Ambry Genetics | RCV004948911 | SCV005510169 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-09-08 | criteria provided, single submitter | clinical testing | The p.N226S variant (also known as c.677A>G), located in coding exon 5 of the STK11 gene, results from an A to G substitution at nucleotide position 677. The asparagine at codon 226 is replaced by serine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. |
