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.762C>T variant (also known as p.P254P), located in coding exon 6 of the STK11 gene, results from a C to T substitution at nucleotide position 762. This nucleotide substitution does not change the proline at codon 254. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
