In contrast, the CC genotype was associated with a predisposition to severe SARS in the Hong Kong population [6] . The exact mechanism of how the minor allele (T) is susceptible to SARS-CoV-2 infection is unknown. Further, we noticed a significant positive correlation between death due to SARS CoV-2 infection and the A c c e p t e d M a n u s c r i p t minor allele T. As the allele T has been associated with elevated sCD14 levels [2] , SARS CoV-2 infected subjects harboring the minor allele (T) possibly produce elevated sCD14, exacerbated inflammatory molecules and ultimately may lead to the poor prognosis of the patients. The present study has several limitations. First, the analysis was performed in European countries. Other continents were not included in the current investigation due to the smaller number of published reports available in the prevalence of CD14 (C-159T) genotypes among the healthy controls (Asia: 10, Africa: 2, Australia: 2, North America: 4 and South America: 1). Second, we performed an observational correlation study to investigate the possible association of SARS CoV-2 infection and mortality; however, the case-control method is most appropriate for genetic predisposition studies. Third, other confounding factors for SARS-CoV-2 related deaths such as age, gender, health facilities, were not evaluated in the present investigation. Based on the the present study and results of the earlier reports, it can be presumed that the T allele of CD14 -159 polymorphism is predisposed to SARS-CoV-2 infection and related mortality. However, case-control studies in different ethnic groups, including larger sample sizes, are required to validate our findings.
