In this study, consecutive serum samples collected from two patients with chronic hepatitis C infection were tested by two assays used widely, the Abbott RealTime HCV Genotype II and the Versant HCV Genotype 2.0 assays, in order to assign a genotype to the virus. The obtained results were verified by phylogenetic analysis of the NS5B region and sequencing of the 5'-UTR of the viral genome. Testing of the serum samples from both patients gave an indeterminate result with the Abbott assay. By contrast, the Versant assay gave an indeterminate result for one patient and identified an HCV-2b subtype in the other patient. Phylogenetic analysis of the NS5B region confirmed the presence of HCV-2b in this latter patient and disclosed the presence of HCV-3h in the other patient. Sequencing of the 5'-UTR revealed the presence of nucleotide changes at positions -166 and -119 of HCV-2b, and at positions -138, -108 and -99 of HCV-3h. Nucleotide mutations located in the 5'-untraslated region of hepatitis C virus may impair the ability of commercial assays to assign an HCV genotype.","is_dataset_classified":null,"base_score":2.639057329615259,"endowment":2.639057329615259,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23791962","pmcid":null,"openalex_id":"https://openalex.org/W2008024230","authors":[],"funders":[{"funder_name":"AVIRALIA Foundation","grant_id":"","title":null},{"funder_name":"Italian National Institute of Health, the Italian Ministry of Instruction University and Research (MIUR)","grant_id":"","title":null},{"funder_name":"“Progetto FILAS”","grant_id":"","title":null}],"total_grants":3,"fwci":1.336,"citation_percentile":0.80066706,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2014,"count":3},{"year":2015,"count":2},{"year":2016,"count":3},{"year":2017,"count":1},{"year":2018,"count":2},{"year":2019,"count":1}],"oa_status":"green","license":"cc-by-nc-nd","oa_locations":[{"url":"http://hdl.handle.net/2108/75671","host_type":"repository"},{"url":"http://hdl.handle.net/2108/75671","host_type":"repository"},{"url":"https://api.elsevier.com/content/article/PII:S0166093413002152?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0166093413002152?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.jviromet.2013.06.002","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/23791962","host_type":"repository"}],"fields_of_study":["Hepatitis C virus research","Liver Disease Diagnosis and Treatment","Hepatitis B Virus Studies","5' Untranslated Regions","Aged","Female","Genotype","Hepacivirus","Hepatitis C, Chronic","Humans","Male","Middle Aged","Molecular Diagnostic Techniques","Phylogeny","Polymorphism, Genetic","Sequence Analysis, DNA","Viral Nonstructural Proteins","Virology","RNA-Dependent RNA Polymerase"],"mesh_terms":["Aged","Female","Genotype","Humans","Male","Middle Aged","Phylogeny","Polymorphism, Genetic","RNA-Dependent RNA Polymerase","Virology","Hepacivirus","Viral Nonstructural Proteins","Sequence Analysis, DNA","Hepatitis C, Chronic","5' Untranslated Regions","Molecular Diagnostic Techniques"],"keywords":["NS5B","Genotype","Hepatitis C virus","Biology","Virology","Hepacivirus","Untranslated region","Flaviviridae","Virus","Hepatitis C","Phylogenetic tree","Genetics","Gene","RNA","Hcv Genotyping","Hcv Polymorphisms","Hcv Real-time","Innolipa"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-12T22:48:13.350805Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
