Genes affected

STK11 (HGNC:11389): (serine/threonine kinase 11) The protein encoded by this gene is a serine/threonine kinase that regulates cell polarity and energy metabolism and functions as a tumor suppressor. Mutations in this gene have been associated with the autosomal dominant Peutz-Jeghers syndrome, as well as with skin, pancreatic, and testicular cancers. [provided by RefSeq, May 2022]

Peutz-Jeghers syndrome

Uncertain:3Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	Genome-Nilou Lab	Jul 15, 2021	- -
Likely benign, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	May 16, 2024	- -
Uncertain significance, criteria provided, single submitter	clinical testing	All of Us Research Program, National Institutes of Health	Mar 14, 2024	This missense variant replaces glycine with serine at codon 346 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 reported for this variant. This variant has been reported in 2 cases and 4 controls in a large breast cancer association study (PMID: 33471991, https://databases.lovd.nl/). This variant has been identified in 3/243724 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	St. Jude Molecular Pathology, St. Jude Children's Research Hospital	Mar 27, 2023	The STK11 c.1036G>A (p.Gly346Ser) missense change has a maximum subpopulation frequency of 0.014% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant was reported in 2 of 60,466 individuals with breast cancer and in 4 of 53,461 controls (PMID: 33471991). This variant is absent in a database of women older than 70 years of age who have never had cancer (FLOSSIES, https://whi.color.com/). To our knowledge, this variant has not been reported in individuals with Peutz-Jeghers syndrome. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 21, 2017	This variant is denoted STK11 c.1036G>A at the cDNA level, p.Gly346Ser (G346S) at the protein level, and results in the change of a Glycine to a Serine (GGC>AGC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. STK11 Gly346Ser was not observed at a significant allele frequency in the NHLBI Exome Sequencing Project. Since Glycine and Serine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. STK11 Gly346Ser occurs at a position that is conserved across species and is located in the c-terminal domain (Hearle 2006). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether STK11 Gly346Ser is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	May 10, 2021	Variant summary: STK11 c.1036G>A (p.Gly346Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 243724 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, c.1036G>A has not been reported in the literature in individuals affected with Peutz-Jeghers Syndrome. However, a recent large-scale breast cancer (BrC) study reported the variant in 2/60466 BrC cases and 4/53461 healthy controls (see Dorling_2021, through LOVD). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and all of them classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Uncertain:1Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Sep 18, 2023	This missense variant replaces glycine with serine at codon 346 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 reported for this variant. In a large breast cancer case-control study, this variant has been reported in 2/60466 cases and 4/53461 controls (PMID: 33471991). This variant has been identified in 3/243724 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. -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 21, 2023	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. -
