Additionally, DBP rs7041 polymorphism is related to the pathogenesis of various infectious diseases, such as coronavirus disease 2019 (COVID-19) (Karcioglu Batur and Hekim, 2020), susceptibility to HCV infection (Xie et al., 2018), chronic hepatitis C progression (Petta et al., 2013; Azevedo et al., 2017), respiratory syncytial virus bronchiolitis (Randolph et al., 2014) and AIDS progression in ART-naïve HIV-infected patients (Eales et al., 1987), as well as the response to antiviral therapy in HCV-infected patients (Falleti et al., 2012). Here, DBP is linked to respiratory syncytial virus bronchiolitis.
