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]

STK11-related disorder Uncertain:1
Mar 27, 2024
PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The STK11 c.1088C>A variant is predicted to result in the amino acid substitution p.Thr363Asn. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00090% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/818352/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Hereditary cancer-predisposing syndrome Uncertain:1
Mar 29, 2022
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.T363N variant (also known as c.1088C>A), located in coding exon 8 of the STK11 gene, results from a C to A substitution at nucleotide position 1088. The threonine at codon 363 is replaced by asparagine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
