| Ambry Genetics | RCV000570526 | SCV000664349 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-04-22 | criteria provided, single submitter | clinical testing | The p.M18I variant (also known as c.54G>A), located in coding exon 1 of the STK11 gene, results from a G to A substitution at nucleotide position 54. The methionine at codon 18 is replaced by isoleucine, an amino acid with highly similar properties. This alteration was seen in 0/732 breast cancer patients, 0/189 colorectal cancer patients and 1/490 cancer-free elderly controls in a Turkish population (Akcay IM et al. Int J Cancer, 2021 01;148:285-295). 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. |

| Invitae | RCV001219409 | SCV001391345 | uncertain significance | Peutz-Jeghers syndrome | 2023-09-25 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 18 of the STK11 protein (p.Met18Ile). This variant is present in population databases (rs755436889, gnomAD 0.0009%). 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: 480711). 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. 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. |
