Human diseases caused by Grin2a 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 Grin2a by orthology or direct annotation.

The table below shows human diseases predicted to be associated to Grin2a by phenotypic similarity.
