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 -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 19-1226536-G-A is Benign according to our data. Variant chr19-1226536-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 184895.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-1226536-G-A is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-1.62 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 21 AD gene.

Submissions by phenotype

not specified Benign:2

Likely benign, criteria provided, single submitter	clinical testing	GeneDx	Sep 11, 2017	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. -
Likely benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jul 22, 2020	- -

Hereditary cancer-predisposing syndrome Benign:2

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 18, 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. -
