Comment on list classification: Updated rating from Red to Green. Although not all studies agree on the association of specific HLA-B alleles and SARS infection (e.g. PMIDs 12969506, 15243926), these studies do both report an association. PMID:18186801 do not report an association between tested HLA-B alleles and SARS development, but on balance in-silico evidence also suggests that HLA-B alleles could play a role in modifying the response to the virus. Therefore Green rating is appropriate for this research panel.

PMID:32303592 (Nguyen et al., 2020) performed in-silico analysis of viral-binding affinity across HLA genotypes for SARS-CoV-2 peptides. Based on in-silico results, they suggest that individuals with HLA-B*46:01 may be vulnerable to COVID-19. Conversely, HLA-B*15:03 may enable greater immunity.

PMID:14595411. Chiu et al, 2003 reviews evidence from PMID:12969506 (Li et al, 2003) that genetic variant HLA-B*4601 might render some groups of people more susceptible to SARS infection. The HLA-B*4601 allele is found in about 10% of the Taiwanese population. 65 suspected SARS patients were tested, so a relatively small study.

The study published in PMID: 12969506 looked at Tawainese patients. PMID: 15243926 looked at 90 patients from Hong Kong who were all genetically unrelated Chinese (18 of these patients had a history of admissions to ICUs and 7 died during the SARS episode). This study identified a strong association between HLA-B*0703 (OR = 4.08; 95% CI, 2.03–8.18; P = 0.00072 [Bonferroni-corrected P value, Pc<.0022]) and the development of SARS. This study did not find any association between HLA-B*4601 and SARS (found in PMID: 12969506).
PMID: 18186801 looked at samples from 95 SARS patients and 403 healthy controls. The cohort of SARS-recovered patients were from Guangzhou and Shenzhen (Southern China) and all are unrelated ethnic Chinese. The healthy controls were sex‐ and age‐matched from in the same geographical area. This study did not find any association between HLA-A, HLA-B and HLA-DRB1 alleles and the development of SARS.

PMID: 12969506 - HLA-B*4601 (OR = 2.08, P = 0.04, Pc = n.s.) and HLA-B*5401 (OR = 5.44, P = 0.02, Pc = n.s.) were associated with SARS coronavirus infection. Looking at the most severe cases of infection, the severity of SARS was shown to be significantly associated with HLA-B*4601 (P = 0.0008 or Pc = 0.0279).
