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]

Benign, criteria provided, single submitter	clinical testing	Myriad Genetics, Inc.	Apr 13, 2023	This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -

Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Sep 30, 2016	Variant summary: The STK11 c.357C>T (p.Asn119Asn) variant causes a synonymous change involving a non-conserved nucleotide with 5/5 splice prediction tools predicting no significant impact on normal splicing. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 10/120328 (1/12032), which is approximately 13 times the estimated maximal expected allele frequency for a pathogenic STK11 variant 1/158730 (0.0000063), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories have classified this variant as benign/likely benign. One internal sample carrying this variant also carries another likely pathogenic variant RAD51C c.93delG, further supporting the benign outcome. Taken together, this variant is classified as Benign. -

Benign:4

Benign, criteria provided, single submitter	clinical testing	GeneDx	Jan 23, 2014	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
