ABSTRACT
Objective@#To explore the virulence related risk factors based on the enterovirus A71 (EV-A71) genome.@*Methods@#The pairwise distance of each section of gene between mild and fatal cases was analyzed. The ⅴ domain of 5′UTR from mild and fatal cases in this study were constructed. Amino acid sequences of EV-A71 were analyzed to find the potential virulence regions which were statistically different between fatal and mild cases.@*Results@#The two EV-A71 genome sequences in this study belonged to C4a genotype with the genomic homology of 96.2%-97.5%. The nucleotides in the ⅴ domains of the 5 ′UTR of EV-A71 from mild and fatal cases were the same. Each gene of EV-A71 from 31 mild cases and 30 fatal cases shared high homology. A total of four potential virulence sites (2 A R68 M、2C K41R、3 A T/V47 A and 3C I158 V) which were significantly different between mild cases and fatal cases were obtained.@*Conclusions@#The four sites in the unstructured protein coding region might be related with the virulence of EV-A71.
