Bioinformatics analysis of HBV s gene mutation in blood donor
Journal Title: Chinese Journal of Blood Transfusion - Year 2024, Vol 37, Issue 8
Abstract
Objective To analyze the infectious indicators, HBV s gene mutations and changes in bioinformatics characteristics of HBV DNA+ /HBsAg- blood donor. Methods A sample of HBV DNA+ /HBsAg- was screened by PCR method, and HBsAg/HBsAb/HBeAg/HBeAb/HBcAb of HBV in the sample were detected by ELISA and chemiluminescence methods. The mutation of the HBVs gene fragment in the sample was sequenced and analyzed, and the bioinformatics analysis was performed using analysis software. Results The sample showed HBV DNA+, HBsAg-, HBsAb+, HBeAg+, HBeAb- and HBcAb+, with an amino acid unit point mutation (P151L) occurred in the HBV s gene, and the spatial structure changed. Conclusion The spatial structural changes in the gene sequence of HBVs may be the reason for the appearance of serological HBsAg-/HBsAb+ /HBV DNA+ in the test results.
