NS3 amino acid polymorphisms were assessed at amino acid positions 36, 43, 54, 55, 56, 80, 122, 155, 156, and 168 relative to the respective subtype-specific reference sequence.
Values were determined in ≥3 independent transient-transfection assays.
IQR, interquartile range.
None, there were no polymorphisms relative to the subtype-specific reference sequence at the amino acid positions assessed.
