<20x FS , likely susceptible
20-100X FS, resistance possible
>100 FS, resistance likely
Multiple RASs:
Data for variants with multiple mutations take precedence over est. from individual RASs
If variant data is not available, follow rules for individual RASs in the variant
2 likely susceptible = likely susceptible
2 resistance possible = resistance likely
likely susceptible + resistance possible = resistance possible
>/= 1 resistance likely RASs = resistance likely
Clinical RAV:
wihtout data but observed in Clinical VF = resistance possible
likely susceptible RASs + clinical RAV = resistance possible
resistance possible RASs + clinical RAV = resistance likely
Positions monitored for "Mutations Detected, effects unknown"

For NGS data: only RASs with >/=2% frequency with be included
EASL 2016 guidelines: NS5a Class RASs, EASL recommends modified Rx
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.
