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]

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 30, 2014	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

The STK11 p.Pro294= variant was not identified in the literature nor was it identified in the MutDB, LOVD 3.0, Zhejiang Colon Cancer Database, Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs587781178) â€šÃ„ÃºWith Likely benign allele,â€šÃ„Ã¹ ClinVar (as benign by GeneDx and likely benign by Ambry Genetics and Invitae), Clinvitae, and Cosmic databases. The variant was identified in control databases in 4 of 169630 chromosomes at a frequency of 0.000024 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.Pro294= 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 addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. 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. -
