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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces arginine with glutamine at codon 42 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 not been reported in individuals affected with STK11-related disorders in the literature. This variant has not been identified 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R42Q variant (also known as c.125G>A), located in coding exon 1 of the STK11 gene, results from a G to A substitution at nucleotide position 125. The arginine at codon 42 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 42 of the STK11 protein (p.Arg42Gln). 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: 234700). 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 with a negative predictive value of 95%. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is denoted STK11 c.125G>A at the cDNA level, p.Arg42Gln (R42Q) at the protein level, and results in the change of an Arginine to a Glutamine (CGG>CAG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. STK11 Arg42Gln was observed with an allele frequency of 0.1% in the European populations in 1000 Genomes. Since Arginine and Glutamine differ in some properties, this is considered a semi-conservative amino acid substitution. STK11 Arg42Gln occurs at a position where amino acids with properties similar to Arginine are tolerated across species and is not located in a known functional 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 Arg42Gln is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
