Data of mutations is necessary for the fact that affinity and specificity brought by variants plays an important role in the engineered TCRs and vaccines design. In TRAIT, a total of 1,031 TCR/antigen mutants are displayed on the "mutations" page to analyze their specific recognition traits and benefit immunotherapies.

• 29 TCRs have been related to their mutations, and detailed information can be accessed by clicking on the TCR name.
• 25 pMHCs have been related to their mutations, and detailed information can be accessed by clicking on the peptide name.
