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.598-7G>A variant was not identified in the literature nor was it identified in MutDB, Zhejiang University Database or Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs377502057) â€šÃ„ÃºWith Likely benign alleleâ€šÃ„Ã¹, ClinVar (classified as likely benign by Invitae, Counsyl, Quest Diagnostics Nichols Institute San Juan Capistrano, and Color Genomics Inc.), Cosmic (1x in a carcinoma of the prostate), and LOVD 3.0 (1x). The variant was also identified in control databases in 17 of 223852 chromosomes at a frequency of 0.00008 (Genome Aggregation Database Feb 27, 2017); the variant was observed in the following populations: European Non-Finnish in 14 of 97910 chromosomes (freq: 0.0001), Latino in 1 of 29348 chromosomes (freq: 0.00003), and South Asian in 2 of 26370 chromosomes (freq: 0.00008), while not observed in the African, Other, Ashkenazi Jewish, East Asian or Finnish populations. The c.598-7G>A variant is located in the 3' splice region but does not affect the invariant -1 and -2 positions. Although positions -3 and -5 to -12 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing, 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
