Human diseases caused by Crb2 mutations

The analysis uses data from IMPC, along with published data on other mouse mutants, in comparison to human disease reports in OMIM, Orphanet, and DECIPHER.

Phenotype comparisons summarize the similarity of mouse phenotypes with human disease phenotypes.

The table below shows human diseases associated to Crb2 by orthology or direct annotation.
