Abstract |
|---|
To investigate if other genetic factors of innate immunity might influence susceptibility and/or progression in individuals infected with SARS, we further evaluated CD14 gene polymorphism in 198 Hong Kong blood donors and 152 Hong Kong SARS patients who were previously genotyped for Fc
RIIA polymorphisms. The prevalence of the CD14-159CC was significantly higher in the severe SARS patients than in the mild SARS group or controls (31% vs. 15% or 20%; P = 0.029; OR: 2.74; 95% CI1.15-6.57 or P = 0.04; OR: 2.41; 95% CI 1.05-5.54, respectively), and both CD14-159CC and Fc
RIIA-RR131 are risk genotypes for severe SARS-CoV infection.
