Immune diversity (HLA) in 2020: COVID outcome disparities
MHC/HLA loci are among the most diverse in the genome — within communities, not between cartoon races. Keep Immune diversity (HLA) with “COVID outcome disparities” and 22 from 2020. Models suggest infection pressures help maintain many alleles; stories remain actively tested.
Transplant medicine matches alleles, not folk races. Use this page to deflate “racial immunity” talk. Human immune genetics is individual and local. Folk races are bad medical categories. Pathogen pressure and mating patterns maintain many alleles. Outcomes track exposure, comorbidity and health systems more than mystical race immunity.
Matching is allelic; ancestry may correlate weakly but clinicians type alleles. See malaria-adaptations — classic selection stories, still not a league of types. Public health logistics beat genetic fatalism. Malaria-adaptations; genetic-structure; race-is-not-biology. Genetic immunology data is sensitive — consent matters.
HLA molecules present peptides to T cells; many alleles mean many presentation styles. Heterozygote advantages are often hypothesized under infection pressure. Linkage disequilibrium complicates stories. Clinical typing beats self-identified race. Allele frequencies differ by region because epidemics and demography differed.
Fold the league table. Keep 2020, “COVID outcome disparities,” and 22 for Immune diversity (HLA). Keep Immune diversity (HLA) with “COVID outcome disparities” and 22 from 2020. 222020
