Viral genome wide association study identifies novel hepatitis C virus polymorphisms associated with sofosbuvir treatment failure

Sofosbuvir is a common therapy in hepatitis C virus infection, which targets the NS5B polymerase. Here, Smith et al. analyze the association between whole genome HCV polymorphisms and sofosbuvir treatment failure and identify three common polymorphisms pre ...

Whole-exome Sequencing for the Identification of Rare Variants in Primary Immunodeficiency Genes in Children With Sepsis: A Prospective, Population-based Cohort Study

Jacques Fellay, Christian Axel Wandall Thorball, Alessandro Borghesi, Nimisha Chaturvedi, Samira Asgari

Background. The role of primary immunodeficiencies (PID) in susceptibility to sepsis remains unknown. It is unclear whether children with sepsis benefit from genetic investigations. We hypothesized that sepsis may represent the first manifestation of under ...

Adaptation of hepatitis C virus to interferon lambda polymorphism across multiple viral genotypes

Jacques Fellay, Nimisha Chaturvedi

Genetic polymorphism in the interferon lambda (IFN-lambda) region is associated with spontaneous clearance of hepatitis C virus (HCV) infection and response to interferon-based treatment. Here, we evaluate associations between IFN-l polymorphism and HCV va ...

HIV peptidome-wide association study reveals patient-specific epitope repertoires associated with HIV control

Jacques Fellay, Nimisha Chaturvedi, Paul Jack Mc Laren

Genetic variation in the peptide-binding groove of the highly polymorphic HLA class I molecules has repeatedly been associated with HIV-1 control and progression to AIDS, accounting for up to 12% of the variation in HIV-1 set point viral load (spVL). This ...

Human genomics of acute liver failure due to hepatitis B virus infection: An exome sequencing study in liver transplant recipients

Jacques Fellay, Christian Hammer, Nimisha Chaturvedi, Petar Scepanovic, Samira Asgari

Acute liver failure (ALF) or fulminant hepatitis is a rare, yet severe outcome of infection with hepatitis B virus (HBV) that carries a high mortality rate. The occurrence of a life-threatening condition upon infection with a prevalent virus in individuals ...

Genetics of human susceptibility to active and latent tuberculosis: present knowledge and future perspectives

Jacques Fellay, Nimisha Chaturvedi

Tuberculosis is an ancient human disease, estimated to have originated and evolved over thousands of years alongside modern human populations. Despite considerable advances in disease control, tuberculosis remains one of the world's deadliest communicable ...

Genome-to-genome analysis highlights the effect of the human innate and adaptive immune systems on the hepatitis C virus

Jacques Fellay, Istvan Bartha, Nimisha Chaturvedi, David Smith

Outcomes of hepatitis C virus (HCV) infection and treatment depend on viral and host genetic factors. Here we use human genome-wide genotyping arrays and new whole-genome HCV viral sequencing technologies to perform a systematic genome-to-genome study of 5 ...
