| alpha-1 | string | one |  |  | The sequence, in amino acid terms, of the first TCR alpha chain, if present | 
| alpha-2 | string | one |  |  | The sequence, in amino acid terms, of the second TCR alpha chain, if present | 
| beta | string | one |  |  | The sequence, in amino acid terms, of the TCR beta chain, if present | 
| id | string | one |  |  | The ID of the TCR, formed as a string by combining the tcr-alpha-1, tcr-alpha-2, and tcr-beta
                          separated by /, prefer nucleotide sequence if present, but if not available fall back to AA seq. |
