19-1207077-TG-TGG
Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000455.5(STK11):c.169dup(p.Glu57GlyfsTer106) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. L55L) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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]

Peutz-Jeghers syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 03, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 93096). This premature translational stop signal has been observed in individual(s) with Peutz-Jeghers syndrome (PMID: 9428765, 20435009). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu57Glyfs*106) in the STK11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in STK11 are known to be pathogenic (PMID: 15188174, 16287113). - |

Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 08, 2015 | The c.169dupG pathogenic mutation, located in coding exon 1 of the STK11 gene, results from a duplication of G at position 169, causing a translational frameshift with a predicted alternate stop codon. In one study, this mutation was reported in an individual suspected to have Peutz-Jeghers syndrome (PJS) (Hemminki A et al Nature. 1998 Jan 8;391(6663):184-7). In addition to the clinical data presented in the literature, since frameshifts are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). - |
