Increased HLA-B Heterozygosity with Age

Abstract
Healthy individuals (427) ranging in age from 16-101 yr were tested for HLA-A and -B antigens. No significant differences were found for any particular antigen according to the age of the individual. A significant trend of increasing frequency with age was found for individuals possessing 2 detectable HLA-B antigens. An apparent trend of increasing frequencies for individuals possessing 4 HLA-A and -B antigens was not significant. These results concur with those of some previously published studies.
