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]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BP6: Variant 19-1220445-G-A is Benign according to our data. Variant chr19-1220445-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 187230.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Peutz-Jeghers syndrome Benign:6

Benign, criteria provided, single submitter	clinical testing	Myriad Genetics, Inc.	Apr 12, 2023	This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -

Likely benign, criteria provided, single submitter	clinical testing	Counsyl	Mar 26, 2018	- -

Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The STK11 p.Pro179= variant was not identified in the literature nor was it identified in the LOVD 3.0, database. The variant was identified in dbSNP (rs528535500) as “with likely benign, other allele” and ClinVar (classified as likely benign by Invitae, Color, Ambry Genetics and 2 other submitters and benign by GeneDx). The variant was identified in control databases in 3 of 235,520 chromosomes at a frequency of 0.00001 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 13,916 chromosomes (freq: 0.000072), East Asian in 1 of 17,286 chromosomes (freq: 0.00006), Finnish in 1 of 20,240 chromosomes (freq: 0.00005), while the variant was not observed in the Latino, Ashkenazi Jewish, European, Other and South Asian populations. The p.Pro179= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs at a non-highly conserved nucleotide 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. -

Likely benign, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Apr 27, 2016	- -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Dec 02, 2014	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Aug 14, 2015

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. -
