The results suggest that HLA-B*44:03 or other closely linked gene of the major histocompatibility complex is associated with susceptibility to the development of PHN after HZ, but not with the onset of HZ.
This work shows that the alleles HLA-A*33 and HLA-B*44 are significantly enriched in PHN patients, while HLA-A*02 and HLA-B*40 are significantly depleted.
