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]

Likely benign, criteria provided, single submitter	clinical testing	Genome-Nilou Lab	Jul 15, 2021	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 12, 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. -

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. -

STK11, EXON2, c.374+11C>T, r.(spl?), Heterozygous, Likely BenignrnThe STK11 c.374+11C>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: rs368923696) and in ClinVar (1X benign by GeneDx, 2X likely benign by Color and Prevention Genetics, and 2X as uncertain by Counsyl and Illumina). The variant was identified in control databases in 19 of 279962 chromosomes at a frequency of 0.00007 (Genome Aggregation Database Feb 27, 2017). This observed frequency is greater than the reported frequency of Peutz Jegher Syndrome suggesting that this variant is too common to be pathogenic for this condition. The variant was observed in the following populations: East Asian in 10 of 19522 chromosomes (freq: 0.0005), South Asian in 5 of 30600 chromosomes (freq: 0.0002), Other in 1 of 7128 chromosomes (freq: 0.0001), African in 2 of 24154 chromosomes (freq: 0.00008), European (non-Finnish) in 1 of 127982 chromosomes (freq: 0.000008); it was not observed in the Latino, Ashkenazi Jewish, or Finnish populations. The variant occurs outside of the splicing consensus sequence and 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. Assessment Date: 2019/06/24. -
