Human diseases caused by Otop1 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.

No human diseases associated to this gene by orthology or annotation.

The table below shows human diseases predicted to be associated to Otop1 by phenotypic similarity.
