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]

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -

Review Status: no assertion criteria provided

Collection Method: clinical testing

The STK11 p.His345= variant was not identified in the literature nor was it identified in the following databases: LOVD 3.0, Zhejiang Colon Cancer Database, Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs751619208) as With Likely benign allele and ClinVar (classified as likely benign by Ambry Genetics, Invitae, Clunsyl, Color Genetics) databases. The variant was identified in control databases in 12 of 272030 chromosomes at a frequency of 0.000044 (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include African in 1 of 23368 chromosomes (freq: 0.00004), European Non-Finnish in 10 of 124322 chromosomes (freq: 0.0001), and South Asian in 1 of 30224 chromosomes (freq: 0.00003), while the variant was not observed in the Other, Latino, Ashkenazi Jewish, East Asian, European Finnish populations. The p.His345= 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. -
