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]

Uncertain significance, criteria provided, single submitter	clinical testing	Counsyl	Apr 13, 2016	- -
Uncertain significance, criteria provided, single submitter	clinical testing	All of Us Research Program, National Institutes of Health	Dec 13, 2023	This missense variant replaces threonine with methionine at codon 367 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). Functional studies have shown that this variant retains STK11 auto-phosphorylation and growth arrest activities, but may be partially impaired for STK11-mediated activation of the AMPK pathway, nuclear export, and establishment and maintenance of cell polarity (PMID: 10676634, 15800014). This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 5/273450 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	Mar 06, 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. -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Published functional studies are inconclusive: decrease in nucleus export efficiency and impairment of LKB1-mediated activation of the AMPK pathway with kinase activity, autophosphorylation, cellular localization, and colony formation similar to wild type (Launonen et al., 2000; Forcet et al., 2005); This variant is associated with the following publications: (PMID: 9731485, 14518068, 18774945, 26798439, 15800014, 10676634, 28900777) -
