Click on the target name to link to its detailed view page
Where available, information is display on the role of the target in the disease; drugs which target the disease and their therapeutic use and side-effects.
If there is mutation data curated in GtoPdb this is indicated, with a link back to the appropriate section on the target detailed view page
Immuno ligand interactions - If available, a table of immuno-relevant ligands is shown. These ligands have been curated as having an association to the disease and possess interaction data with the target in GtoPdb. The approval status of the ligand is shown, along with curator comments and an indication of whether the target is considered the primary target of the ligand.
More information can be found in the help pages.
✖| Kv7.1 | |
| Role: | Loss of function mutations in KCNQ1 (or associated KCNE1 beta-subunits) prolongs action potentials and increases risk of torsades de pointes arrhythmia, fibrillation and sudden death; recessive mutations also cause deafness |
| Drugs: | Activators of KCNQ1 may alleviate condition, but blockers can aggravate LQTS |
| Therapeutic use: | Activators are being explored as potential therapy for LQTS |
| Comments: | For a complete list of all the mutations in KCNQ1 associated with Long QT syndrome 1, please see the OMIM entry. |
