摘要:
To analyze the characteristic of nuclear antigen 1 gene and latent membrane protein 1 gene of Epstein-Barr virus in primary EBV infection in children in Beijing area in 2005-2012. Polymerase chain reaction (PCR) was used to amplify the EBNA-3C, EBNA1 and LMP1 genes. The amplified products were sequenced directly and the sequences were analyzed by BioEdit 7. 0. 9 and MEGA 4. 0. 2. Type A EBV was detected in 98% samples. Nucleotide sequence analysis of the carboxy-terminal region of EBNA1 showed that Vvvl was deteted in 98% samples. DNA sequence analysis of LMP1 C-terminus indicated that China 1 was 90% in this study. There were no significant differences in the frequency of Vvv1 and China 1 between the IM and HLH samples (P = 1.00). Linkage analysis of EBV types, EBNA1 and LMP1 variants indicated that 90% of EBV type A was associated with EBNA1-Vvv1 variant and LMP1-China 1 variant in 40 cases. Full length of LMP1 gene was successfully amplified in 35 cases. Four Chinese groups (CG1-4) were identified. The percentage of CG1-CG4 were 85%, 6%, 6% and 3%, respectively. EBV type A is predominant in primary EBV infection in children in Beijing Area. EBNA1-Vvv1 and LMP1-China 1 variants were predominant genotypes in this area. There is a high linkage between EBNA1-Vvv1 variant and LMP1-China 1 variant. Four Chinese groups (CG1-4) were identified according to the full length of LMP1 gene and CG1 was the most prevalent.
