1. If data are available for the same substitution in both subtypes, use the one indicated with [Use in algorithm] | ||||||
2. If data are available in one subtype but not the other, use the avialable data for all subtypes. Adoption of the reference WT amino aicd might be required Adapted WT is indicated in red. | ||||||
3. some mutations contain conflicting WT e.g. L28F in GT2b; adaption to ref WT will become F28F. The reporting for this type of mutations is temporarily suspended. | ||||||
4. Differential susceptibilities were observed for the same mutations but in different backgrounds (e.g. different isolates of the same subtype, or between 2 different subtypes). The mutation with a higher fold change was chosen to err on the conservative interpretation. |
