| Ambry Genetics | RCV002320808 | SCV002610532 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-08-30 | criteria provided, single submitter | clinical testing | The p.A377G variant (also known as c.1130C>G), located in coding exon 9 of the STK11 gene, results from a C to G substitution at nucleotide position 1130. The alanine at codon 377 is replaced by glycine, 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. |
| Invitae | RCV003507408 | SCV004300610 | uncertain significance | Peutz-Jeghers syndrome | 2023-01-06 | criteria provided, single submitter | clinical testing | 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. ClinVar contains an entry for this variant (Variation ID: 1728176). This variant has not been reported in the literature in individuals affected with STK11-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 377 of the STK11 protein (p.Ala377Gly). |
