Interleukin-28B genotyping by melt-mismatch amplification mutation assay PCR analysis using single nucleotide polymorphisms rs12979860 and rs8099917, a useful tool for prediction of therapy response in hepatitis C patients.

چکیده
Several studies have identified associations between single nucleotide polymorphisms (SNPs) occurring near the interleukin-28B (IL-28B) gene and response to antiviral treatment among hepatitis C virus (HCV) patients. Here, we describe a reliable melt-mismatch amplification mutation assay (melt-MAMA) PCR-based genotyping method for IL-28B which can be used in the management of HCV patients, helping to better define the course of therapy.

BACKGROUND AND AIMS Genetic polymorphisms near interleukin 28B gene are associated with spontaneous and treatment induced clearance of hepatitis C virus (HCV). Our objective was to evaluate the impact of interleukin 28B single nucleotide polymorphism (rs12979860, rs8099917) variability in HCV genotype 3 infected populations. METHODS 400 hepatitis C seroreactive patients from different populat...

HCV infection is a serious public health problem and a leading cause of chronic liver disease. It affects nearly 3% of the world's population with an associated high mortality. Egypt has the highest prevalence of HCV infection in the world (estimated at >10%). Peg-IFN-α and RBV are the most widely used therapy for HCV. Unfortunately, the rate of SVR is around 50%. In addition, it is expensive a...

We focused on determining the most accurate and convenient genotyping methods and most appropriate single nucleotide polymorphism (SNP) among four such polymorphisms associated with interleukin-28B (IL-28B) in order to design tailor-made therapy for patients with chronic hepatitis C virus (HCV) patients. First, five different methods (direct sequencing, high-resolution melting analysis [HRM], h...
متن کاملRs12979860 and rs8099917 single nucleotide polymorphisms of interleukin-28B gene: simultaneous genotyping in Caucasian patients infected with hepatitis C virus
INTRODUCTION Recent studies have demonstrated the role of the interleukin 28B (IL28B) polymorphisms in predicting treatment induced and spontaneous clearance from Hepatitis C virus (HCV) infection, suggesting the possibility of tailored therapy in HCV infected patients. Genome-wide association studies have shown that single nucleotide polymorphisms (SNPs) near IL 28B gene on chromosome 19 are s...
متن کاملPredicting sustained viral response to hepatitis C using a rapid and simple IL28B rs8099917 genotyping assay.
Recent studies showed that two single nucleotide polymorphisms (SNPs) (rs12979860 and rs8099917) near the gene IL28B coding for IFNλ3 were associated with the antiviral treatment response of the combination therapy of pegIFN plus RBV. We established the use of tetra-primer amplification refractory mutation system polymerase chain reaction (ARMS-PCR) for detecting IL28B rs8099917 genotype (T>G) ...
