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]

Variant summary: STK11 c.735-10C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 2.4e-05 in 247506 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.735-10C>T in individuals affected with Peutz-Jeghers Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -

The STK11 c.735-10C>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: rs553975112) as â€šÃ„ÃºWith Likely benign alleleâ€šÃ„Ã¹ and ClinVar (classified as likely benign by Invitae and Color). The variant was identified in control databases in 5 of 245208 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: East Asian in 3 of 17232 chromosomes (freq: 0.0002, increasing the chances that this is a low frequency benign variant), European Non-Finnish in 1 of 111040 chromosomes (freq: 0.000009), and European Finnish in 1 of 22288 chromosomes (freq: 0.00005), while it was not observed in the African, Other, Latino, Ashkenazi Jewish, or South Asian populations. The c.735-10C>T 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. However, 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. -
