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]

Variant summary: STK11 c.310A>T (p.Arg104Trp) results in a non-conservative amino acid change located in the Protein kinase domain (IPR000719) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 249174 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.310A>T in individuals affected with Peutz-Jeghers Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 142871). Based on the evidence outlined above, the variant was classified as uncertain significance. -

The p.R104W variant (also known as c.310A>T), located in coding exon 2 of the STK11 gene, results from an A to T substitution at nucleotide position 310. The arginine at codon 104 is replaced by tryptophan, an amino acid with dissimilar properties. This variant was reported in 1/60,466 breast cancer cases and in 0/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). This variant has been detected in multiple individuals with no reported features of Peutz-Jeghers syndrome (Ambry internal data). 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. -
