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]

The STK11 c.465-5C>T variant was not identified in the literature nor was it identified in the LOVD 3.0, database. The variant was identified in dbSNP (ID: rs567202367) as â€šÃ„ÃºWith other alleleâ€šÃ„Ã¹ and ClinVar (4x as likely benign and 1x as uncertain significance by Ambry Genetics, Invitae, Counsyl, Color and The Children Hospital of Philadelphia). The variant was identified in control databases in 1 of 30916 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: East Asian in 1 of 1622 chromosomes (freq: 0.0006), while the variant was not observed in the African, Other, Latino, European Non-Finnish, Ashkenazi Jewish, European Finnish or South Asian populations. The c.465-5C>T variant is located in the 3' splice region but does not affect the invariant -1 and -2 positions. However, positions -3 and -5 to -12 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. In addition in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) 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. This variant is classified as a variant of uncertain significance. -
