Description
Corneal abnormalities inclusion criteria (29586)
- Bilateral corneal signs
- Prior consultation with ophthalmologist who has a specialist interest in corneal dystrophies

Corneal abnormalities exclusion criteria (29586)
- Corneal opacity likely secondary to inflammatory disease or trauma (including surgical)
- Age-related corneal endothelial failure
- Keratoconus

Prior genetic testing guidance (29586)
- Results should have been reviewed for all genetic tests undertaken, including disease-relevant genes in exome sequencing data. The patient is not eligible if they have a molecular diagnosis for their condition. 
- Genetic testing should continue according to routine local practice for this phenotype regardless of recruitment to the project; results of these tests must be submitted via the ‘Genetic investigations’ section of the data capture tool to allow comparison of WGS with current standard testing.  

PLEASE NOTE: The sensitivity of WGS compared to current diagnostic genetic testing has not yet been established. It is therefore important that tests which are clinically indicated under local standard practice continue to be carried out.

Corneal abnormalities prior genetic testing genes (29586)
Testing of the following genes should be carried out PRIOR TO RECRUITMENT where this is in line with current local practice: 
 - TGFBI (BIGH3) gene screening in anterior corneal dystrophies (which accounts for approximately 80% of such families)

Closing statement (29586)
These requirements will be kept under continual review during the main programme and may be subject to change.
