| Invitae | RCV000691840 | SCV000819636 | uncertain significance | Peutz-Jeghers syndrome | 2023-12-08 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 357 of the STK11 protein (p.Glu357Gln). 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: 570868). 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 | RCV002406561 | SCV002720706 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-10-13 | criteria provided, single submitter | clinical testing | The p.E357Q variant (also known as c.1069G>C), located in coding exon 8 of the STK11 gene, results from a G to C substitution at nucleotide position 1069. The glutamic acid at codon 357 is replaced by glutamine, 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. |
