Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000455.5(STK11):c.10G>A(p.Val4Met) variant causes a missense change. The variant allele was found at a frequency of 0.000000699 in 1,431,562 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V4A) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 09, 2022 | The p.V4M variant (also known as c.10G>A), located in coding exon 1 of the STK11 gene, results from a G to A substitution at nucleotide position 10. The valine at codon 4 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is poorly 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. - |
Peutz-Jeghers syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 08, 2024 | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 4 of the STK11 protein (p.Val4Met). 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: 480709). 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. - |
