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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Jan 05, 2023	The frequency of this variant in the general population, 0.00026 (6/23256 chromosomes in African/African American subpopulation, http://gnomad.broadinstitute.org), is higher than would generally be expected for pathogenic variants in this gene. In the published literature, the variant was identified in a cohort of children affected with various solid tumors (PMID: 30455982 (2018)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -

Variant summary: STK11 c.1127A>C (p.Glu376Ala) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.1e-05 in 241804 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1127A>C has been reported in the literature as a VUS in at-least one individual within a cohort of children with malignant pediatric tumors (example, Chan _2018). These report(s) do not provide unequivocal conclusions about association of the variant with Peutz-Jeghers Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 30455982). ClinVar contains an entry for this variant (Variation ID: 127698). Based on the evidence outlined above, the variant was classified as uncertain significance. -
