[Determination of the naturally occurring Q80K mutation in the HCV NS3 protease gene].

Objectives: The aim was to introduce a diagnostic method for detecting variants of hepatitis C virus (HCV) with protease NS3 resistance primarily to simeprevir (Q80K mutation in HCV genotype 1a) and its subsequent use in routine practice.

Material And Methods: The detection of HCV resistance-associated variants in the NS3 protease gene by sequence analysis was introduced in the molecular biology laboratory of University Hospital Hradec Kralove in 2015. The primers were designed by sequence analysis software Custom Primers - OligoPerfect™ Designer.
