Footnote 1: These data have been filtered to exclude redundant data by criteria outlined in the User Manual. As a result, each sequence in the table is from a different patient
Footnote 2: 'AA' indicates that the amino acid sequence is available. 'NA' indicates that both the nucleic acid and amino acid sequences are available
Footnote 2: The numbers in 'Received No Other Drugs' indicate sequences from patients who received only one drug of the drug class indicated in column 1
Footnote 3: The numbers in 'Received Other Drugs' indicate the number of sequences from patients who ever received the drug in column 1
