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. -

The STK11 c.597+14delA variant was not identified in the literature nor was it identified in the Cosmic, MutDB, Zhejiang Colon Cancer Database, or Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs536282050) as â€šÃ„ÃºWith Likely benign allele,â€šÃ„Ã¹ ClinVar (as benign by GeneDx and likely benign by Illumina, Counsyl, and Color Genomics), Clinvitae (2x as in ClinVar), and LOVD 3.0 (2x as likely benign) databases. The variant was identified in control databases in 1 of 30810 chromosomes at a frequency of 0.000032 (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include African in 1 of 8678 chromosomes (freq: 0.000115), while the variant was not observed in the Ashkenazi Jewish, East Asian, European (Finnish), European (Non-Finnish), Latino, Other, and South Asian populations. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The variant was identified with a co-occurring pathogenic NBN variant (p.Lys233SerfsX5), increasing the likelihood that the c.597+14delA variant does not have clinical significance. 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. -
