Les preprints sont des rapports de recherche préliminaires qui n'ont pas été certifiés par l’évaluation par les pairs. Ils ne devraient pas être considérés comme guidant la pratique clinique ou les comportements liés à la santé et ne devraient pas être rapportés dans les médias comme des informations établies.
Les preprints publiées en ligne permettent aux auteurs de recevoir des commentaires rapidement, et toute la communauté scientifique peut évaluer indépendamment le travail et répondre en conséquence.

ABSTRACT
Covid-19 is a contagious disease caused by SARS-CoV-2, a novel severe acute respiratory syndrome coronavirus. Common variants and networks underlying host genetic mechanisms have been extensively studied to identify disease-associated genetic factors. However, there are few studies about the rare variants, typically inborn errors of immunity, in understanding the host genetics behind Covid-19 infection, especially in the Chinese population. To fill this gap, we investigate likely-deleterious missense and high-confidence predicted loss-of-function variants by (a) performing gene- and pathway-level association analyses, (b) examining known genes involved in type I interferon signaling and others previously reported in Covid-19 disease, and (c) identifying candidate genes with accumulating mutations and their potential protein-protein interactions with known genes. Based on our analyses, several putative genes and pathways are uncovered and worth further investigation, for example, genes IL12RB1, TBK1, and TLR3, and pathways Tuberculosis (hsa05152), Primary Immunodeficiency (hsa05340), and Influenza A (hsa05164). These regions generally play an essential role in regulating antiviral innate immunity responses to foreign pathogens and in responding to many inflammatory diseases. We believe that to some extent, as an acute inflammatory disease, Covid-19 is also affected by these inborn errors of immunity. We hope that the identification of these rare genetic factors will provide new insights into the genetic architecture of Covid-19.
