LQTGP - Overview: Long QT Syndrome Multi-Gene Panel, Blood

Test Catalog

Test Name

Test ID: LQTGP    
Long QT Syndrome Multi-Gene Panel, Blood

Useful For Suggests clinical disorders or settings where the test may be helpful

Providing a comprehensive genetic evaluation for patients with a personal or family history suggestive of long QT syndrome (LQTS)

 

Establishing a diagnosis of a LQTS, in some cases, allowing for appropriate management and surveillance for disease features based on the gene involved

 

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

Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request

This test includes next-generation sequencing and supplemental Sanger sequencing to evaluate the genes on this panel.

 

Prior Authorization is available for this assay; see Special Instructions.

 

Targeted testing for familial variants (also called site-specific or known mutation testing) is available for all genes on this panel; see KVAR1 / Known Variant Analysis-1 Variant. Contact Mayo Medical Laboratories to confirm the appropriate test code for targeted testing if testing for a gene not included on this panel, or if testing for more than 1 variant is needed.

Highlights

This test uses next-generation sequencing to test for variants in the AKAP9, ANK2, CACNA1C, CAV3, KCNE1, KCNE2, KCNH2, KCNJ2, KCNJ5, KCNQ1, SCN4B, SCN5A, and SNTA1 genes.

 

This test may aid in the diagnosis of long QT syndrome.

 

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

Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
