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:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

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. -

The STK11 p.Ala206= variant was not identified in the literature nor was it identified in the LOVD 3.0 database. The variant was identified in dbSNP (ID: rs370976710) as "With Likely benign, other allele" and ClinVar (classified as benign by Invitae; as likely benign by Ambry Genetics, GeneDx and Counsyl; and as uncertain significance by one clinical laboratory). The variant was identified in 48 of 240844 chromosomes at a frequency of 0.0002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European in 1 of 107104 chromosomes (freq: 0.000009), Ashkenazi Jewish in 24 of 9264 chromosomes (freq: 0.003), and Finnish in 23 of 22390 chromosomes (freq: 0.001); it was not observed in the African, Other, Latino, East Asian, or South Asian populations. The p.Ala206= 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, although 3 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing. However, this information is not predictive enough to assume pathogenicity. 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. -
