GtoPdb Disease Summaries - Targets
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.
✖| ADGRV1 | |
| Comments: | Usher syndrome type II is a genetically heterogeneous autosomal recessive disorder characterised by hearing loss and retinitis pigmentosa. Several different mutations have been identified in single families. Another mutation has been found in a family with familial febrile seizures. Usher syndrome type IIC can be caused by mutation in genes other than ADGRV1 (formerly GPR98). |
