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 STK11 p.Phe255Phe variant was not identified in the literature nor was it identified in the COSMIC, MutDB, LOVD 3.0, Zhejiang Colon Cancer Database, or Insight Hereditary Tumors Database. The variant was identified in dbSBP (ID: rs769912677) as â€šÃ„ÃºWith Likely benign alleleâ€šÃ„Ã¹, ClinVar (2x likely benign: Ambry Genetics, Invitae), Clinvitae (2x likely benign: Invitae, ClinVar), databases. The variant was identified in control databases in 4 of 276208 chromosomes (3x European non-Finnish, 1x European Finnish) at a frequency of 0.00001 increasing the likelihood that this may be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017). The p.Phe255Phe variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
