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]

The c.-1C>T variant is located in the 5' untranslated region (5’ UTR) of the STK11 gene. This variant results from a C to T substitution 1 bases upstream from the first translated codon. This alteration was identified in a cohort of 1260 individuals undergoing panel testing for Lynch syndrome due to having a diagnosis of a Lynch-associated cancer and/or polyps (Yurgelun MB et al. Gastroenterology, 2015 Sep;149:604-13.e20). This nucleotide position is poorly conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Variant summary: STK11 c.-1C>T is located in the untranslated mRNA region upstream of the initiation codon. The variant allele was found at a frequency of 1.1e-05 in 182860 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.-1C>T has been reported in the literature in individuals affected with Lynch syndrome associated cancer (Yurgelun_2015). These report(s) do not provide unequivocal conclusions about association of the variant with Peutz-Jeghers Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as likely benign, and one laboratory classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
