YMDD and FLLAQ Mutations in Chronic Hepatitis B Patients
Abstract Background and Objective: Lamivudine is the first orally available drug approved for treatment of chronic hepatitis B. Mutations at the YMDD and FLLAQ motifs in the domains of HBV polymerase gene contribute resistance to lamivudine. This study was aimed to determine the rate of YMDD and FLLAQ mutants in hepatitis B patients in Golestan Province, Iran. Material and methods: In this cros...
متن کاملCompensatory variances of drug-induced hepatitis B virus YMDD mutations
Although the drug-induced mutations of HBV have been ever documented, the evolutionary mechanism is still obscure. To deeply reveal molecular characters of HBV evolution under the special condition, here we made a comprehensive investigation of the molecular variation of the 3432 wild-type sequences and 439 YMDD variants from HBV genotype A, B, C and D, and evaluated the co-variant patterns and...
متن کاملHBx Gene Mutations in Hepatitis B Virus and Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is one of the most prevalent cancers which are found in many Asian and African countries. There are several risk factors that may develop to HCC. Along with several other factors contributing to HCC, hepatitis B virus (HBV) infection also accounts for a major cause. HBV infection represents a major health problem worldwide. Among all of HBV genes, HBx is believed ...
متن کاملNaturally Occurring Precore/Core Region Mutations of Hepatitis B Virus Genotype C Related to Hepatocellular Carcinoma
Previous studies have proved the presence of several distinct types of mutations in hepatitis B virus (HBV) infections, which are related to the progression of liver disease. However, few reports have detailed the mutation frequencies and mutation patterns in the precore/core (preC/C) region, which are based on the clinical status and HBeAg serostatus. Our aim in this study is to investigate th...
متن کاملhepatitis b virus core promoter mutations in patients with chronic hepatitis b and hepatocellular carcinoma in bucharest, romania
conclusions genotype d was the main genotype detected in romanian patients with chronic hbv infection. genotype d presented both bcp and pc mutations more frequently. results we detected two hbv genotypes; a (8.1%) and d (60.5%), and a mixture of genotypes a and d (31.4%) (p < 0.001). basal core promoter (bcp) a1762t/g1764a and precore (pc) g1896a mutations were detected in these romanian patie...
