CRP and COVID-19: Due to the correlation between severity of COVID-19 disease and CRP levels, which indicate a more severe infection, as well as the correlation between elevated CRP levels in blood and SNPs in the CRP gene, this study examined two SNPs in the CRP gene (rs1205 and rs1800947) in order to determine how host genetic factors influence COVID-19 severity according to SARS-CoV-2 variations.
