Test ID STK1Z Peutz-Jeghers Syndrome, STK11, Full Gene Analysis, Varies

Ordering Guidance

For a comprehensive hereditary cancer panel that includes the STK11 gene, consider 1 of the following tests:

-CRCGP / Hereditary Gastrointestinal Cancer Panel, Varies

-BRGYP / Hereditary Breast/Gynecologic Cancer Panel, Varies


Testing for STK11 gene as part of a customized panel is available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.


Targeted testing for familial variants (also called site-specific or known mutations testing) is available for this gene. For more information see FMTT / Familial Mutation, Targeted Testing, Varies.

Useful For

Evaluation for patients with a personal or family history suggestive of Peutz-Jeghers syndrome (PJS)


Establishing a diagnosis of PJS allowing for targeted cancer surveillance based on associated risks


Identifying variants within genes known to be associated with increased risk for PJS allowing for predictive testing of at-risk family members

Genetics Test Information

This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 1 gene associated with Peutz-Jeghers syndrome (PJS): STK11. See Method Description for additional details.


Identification of a pathogenic variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for PJS.
