A Phylogeny-aware GWAS Framework to Correct for Heritable Pathogen Effects on Infectious Disease Traits
Jacques Fellay, Christian Axel Wandall Thorball
Infectious diseases are particularly challenging for genome-wide association studies (GWAS) because genetic effects from two organisms (pathogen and host) can influence a trait. Traditional GWAS assume individual samples are independent observations. Howev ...
OXFORD UNIV PRESS2022Polygenic Risk Scores for Prediction of Subclinical Coronary Artery Disease in Persons Living With HIV: The Swiss HIV Cohort Study
Jacques Fellay, Christian Axel Wandall Thorball
Background. In people living with human immunodeficiency virus (HIV) (PLWH), individual polygenic risk scores (PRSs) are associated with coronary artery disease (CAD) events. Whether PRSs are associated with subclinical CAD is unknown. Methods. In Swiss HI ...
OXFORD UNIV PRESS INC2022Host genomics of SARS-CoV-2 infection
Jacques Fellay, Christian Axel Wandall Thorball
SARS-CoV-2 infected a large fraction of humans in the past 2 years. The clinical presentation of acute infection varies greatly between individuals, ranging from asymptomatic or mild to life-threatening COVID-19 pneumonia with multi-organ complications. De ...
SPRINGERNATURE2022A highly virulent variant of HIV-1 circulating in the Netherlands
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log(10) increase (i.e., a similar to 3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited ...
AMER ASSOC ADVANCEMENT SCIENCE2022The combined impact of persistent infections and human genetic variation on C-reactive protein levels
Jacques Fellay, Olivier Noël Marie Naret, Flavia Aurelia Shoko Hodel, Clara Bonnet
Multiple human pathogens establish chronic, sometimes life-long infections. Even if they are often latent, these infections can trigger some degree of local or systemic immune response, resulting in chronic low-grade inflammation. There remains an incomple ...
BMC2022Variability of Primary Sjogren's Syndrome Is Driven by Interferon alpha and Interferon alpha Blood Levels Are Associated With the Class II HLA-DQ Locus
Jacques Fellay, Christian Axel Wandall Thorball, Nicolas Meyer
Objective Primary Sjogren's syndrome (SS) is the second most frequent systemic autoimmune disease, affecting 0.1% of the general population. To characterize the molecular and clinical variabilities among patients with primary SS, we integrated transcriptom ...
WILEY2022Using population-specific add-on polymorphisms to improve genotype imputation in underrepresented populations
Jacques Fellay, Zhi Ming Xu, Sina Rüeger
Genome-wide association studies rely on the statistical inference of untyped variants, called imputation, to increase the coverage of genotyping arrays. However, the results are often suboptimal in populations underrepresented in existing reference panels ...
San Francisco2022The influence of human genetic variation on Epstein–Barr virus sequence diversity
Jacques Fellay, Dylan Lawless, Olivier Noël Marie Naret, Christian Hammer, Sina Rüeger
Epstein–Barr virus (EBV) is one of the most common viruses latently infecting humans. Little is known about the impact of human genetic variation on the large inter-individual differences observed in response to EBV infection. To search for a potential imp ...
2021A high-resolution HLA reference panel capturing global population diversity enables multi-ancestry fine-mapping in HIV host response
Jacques Fellay, John Wilson, Yang Luo, Xinyi Li
A high-resolution reference panel based on whole-genome sequencing data enables accurate imputation of HLA alleles across diverse populations and fine-mapping of HLA association signals for HIV-1 host response. Fine-mapping to plausible causal variation ma ...
NATURE PORTFOLIO2021Human genomics of the humoral immune response against polyomaviruses
Jacques Fellay, Christian Axel Wandall Thorball, Zhi Ming Xu, Olivier Noël Marie Naret, Christian Hammer, Flavia Aurelia Shoko Hodel, Petar Scepanovic
Human polyomaviruses are widespread in humans and can cause severe disease in immunocompromised individuals. To identify human genetic determinants of the humoral immune response against polyomaviruses, we performed genome-wide association studies and meta ...
