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]

Collection Method:clinical testing

The STK11 p.Gln123= variant was not identified in the literature nor was it identified in the Cosmic, MutDB, LOVD 3.0, Zhejiang Colon Cancer Database, and Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs140112347) as “other”, ClinVar (classified as benign/likely benign; submitters: benign by Ambry Genetics, Invitae and Prevention Genetics; likely benign by Illumina Clinical Services Laboratory) and in control databases in 563 (8 homozygous) of 277056 chromosomes at a frequency of 0.002 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017), identified in the following population at a frequency greater than 1%: African in 515 (8 homozygous) of 24002 chromosomes (freq: 0.02) . The p.Gln123= 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. The variant occurs 6 nucleotides from the end of exon 2 and and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of 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. -

Significance:Likely benign
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 allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

This alteration is classified as 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. -
