Molecular genetics of HLA‐DR ‘Br’: allogenotypes of DR1 and DR ‘Br’ are indistinguishable

Abstract

HLA-DR1 and DR 'Br' allogenotype patterns, generated using several restriction endonucleases and visualised using four HLA-DR beta cDNA probes in Southern analysis, are indistinguishable. We suggest that HLA-DR 'Br' may be a variant of the HLA-DR1 allele.
