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 sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 15 of the STK11 protein (p.Gly15Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with pancreatic cancer (PMID: 28767289). ClinVar contains an entry for this variant (Variation ID: 403797). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces glycine with serine at codon 15 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 an individual affected with pancreatic ductal adenocarcinoma in the literature (PMID: 28767289). 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

PM2_Supporting, BP4_moderate c.43G>A, located in exon 1 of the STK11 gene, is predicted to result in the substitution of glycine by serine at codon 15, p.(Gly15Ser). It is not present in the population database gnomAD v2.1.1, non-cancer dataset (PM2_supporting). The SpliceAI algorithm predicts no significant impact on splicing and the REVEL meta-predictor score for this variant (0,066) suggests that it does not affect the protein function according to Pejaver 2022 thresholds (PMID: 36413997)(BP4_moderate). Moreover, it has been identified in the ClinVar (3x uncertain significance, 1x likely benign) and LOVD (2x uncertain significance) databases. Based on currently available information, the variant c.43G>A is classified as an uncertain significance variant according to ACMG guidelines. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. -
