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]

This sequence change affects codon 186¬†of the STK11 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the STK11 protein. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. This variant is present in population databases (rs749563734, ExAC 0.007%) but has not been reported in the literature in individuals with a STK11-related disease. In summary, this is a rare silent change with uncertain impact on splicing. It has been classified as a Variant of Uncertain Significance. -
