В настоящее время установлено, что частота развития ГЦК у больных с 1b генотипом вируса гепатита С (ВГС) была достоверно выше, чем c другими генотипами.При анализе аминокислотных последовательностей у больных с 1b генотипом ВГС выявлены мутации с заменой аргинина на глицин в 70 кодоне (Glu70) и лейцина на метионин в 91 кодоне (Met 91). При этом обнаружено, что мутантный тип Glu 70 встречается достоверно чаще у пациентов с ГЦК по сравнению с больными ХГС и циррозом печени, в более старших возрастных группах, при повышении уровня гамма-глутамилтранспептидазы и аспартатаминотрансферазы в сыворотке крови. Появление мутантных форм 1b генотипа связано с открытием ранее неизвестного белка ВГС — minicor-протеина, при котором отсутствует N-конец классического Corпротеина p21.Заключение. Раннее выявление мутантных Glu 70, Met 91 форм 1b генотипа ВГС позволит прогнозировать риск развития ГЦК у больных ХГС и начать своевременное адекватное этиотропное лечение для профилактики этого грозного осложнения.</p></abstract><trans-abstract xml:lang="en"><sec><title>The aim of review</title><p>The aim of review. To estimate effect of genetic polymorphism of hepatitis C virus on risk of hepatocellular carcinomas (HCC).</p></sec><sec><title>Key points</title><p>Key points. Hepatocellular carcinoma is one of the most dreadful outcomes of chronic liver diseases, in particular — chronic hepatitis C (CHC). Now it is revealed, that frequency of HCC in patients with 1b genotype of hepatitis C virus (HCV) was significantly above, than other genotypes. In aminoacidic sequences analysis in patients with 1b genotype of HCV mutations with substitution of arginine to glycine in codon 70 (Glu 70) and leucine to methionine in codon 91 (Met 91) were revealed. Thus it is revealed, that mutant type Glu 70 is significantly more frequent in patients with HCC in comparison to CHC and liver cirrhosis, in older age groups, at elevation of serum level of gamma-glutamyltranspeptidase and aspartate aminotransferase. Frequency of mutant forms of 1b genotype is related to discovery of previously unknown protein of HCV — minicor-protein with absence of N-terminal of classical Cor-protein p21.</p></sec><sec><title>Conclusion</title><p>Conclusion. Early detection mutant Glu 70, Met 91 forms of HCV genotype 1b will provide prediction of HCC risk in CHC patients and to begin adequate etiological treatment for preventive maintenance of this dangerous complication intime.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гепатоцеллюлярная карцинома</kwd><kwd>хронический гепатит С</kwd><kwd>генотип 1b вируса гепатита С</kwd><kwd>мутации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatocellular carcinoma</kwd><kwd>chronic hepatitis C</kwd><kwd>genotype 1b hepatitis C virus</kwd><kwd>mutations</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гепатоцеллюлярная карцинома (ГЦК): глобальная перспектива.
