Conclusion: Here, we performed genome-wide association analyses on all SARS-CoV-2 genomes in the GISAID database, and found that a mutation at genomic position 11 083, namely the
11083G>T mutation, located in the coding region of non-structural protein 6, is significantly associated with asymptomatic
COVID-19, adjusted for various confounders and covariates, including virus phylogenetic relatedness, patient age, gender and country.
