Variant summary
Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2
The NM_000455.5(STK11):c.1229C>T(p.Ala410Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000202 in 1,585,200 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. A410A) has been classified as Benign.

Peutz-Jeghers syndrome Uncertain:3Benign:1
- -
This missense variant replaces alanine with valine at codon 410 of the STK11 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been performed for this variant. This variant has been reported in individuals affected with breast cancer in the literature (PMID: 30093976, 31871109). This variant has been identified in 5/191680 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Variant summary: STK11 c.1229C>T (p.Ala410Val) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.6e-05 in 191680 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1229C>T has been reported in the literature in individuals reported with breast cancer who have undergone multi gene panel testing (examples: Chan_2018 and Adedokun_2020). These reports classified the variant as VUS and do not provide unequivocal conclusions about association of the variant with Peutz-Jeghers Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as likely benign(n=2) and VUS(n=3). Based on the evidence outlined above, the variant was classified as uncertain significance. -
not provided Uncertain:1Benign:1
The STK11 c.1229C>T (p.Ala410Val) variant has been reported in the published literature in at least one individual with breast cancer (PMID: 30093976 (2018)). It has also been described as a variant of uncertain significance in a breast cancer case-control study (PMID: 31871109 (2019)). The frequency of this variant in the general population, 0.000037 (3/81990 chromosomes in European (Non-Finnish) subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 30093976) -
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
This missense variant replaces alanine with valine at codon 410 of the STK11 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been performed for this variant. This variant has been reported in individuals affected with breast cancer in the literature (PMID: 30093976, 31871109). This variant has been identified in 5/191680 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
