A group of 1522 individuals were HLA-DR-typed both by the standard serological technique and by the RFLP method. Whereas 11% (n = 164) of the serological typings were technically unsuccessful or doubtful, all typings were successful by RFLP. The results of the remaining 1358 typings revealed a serological error rate of 25%. In 16% a serological "blank" turned out to be a definable allele by RFLP, while in 9% an allele was incorrectly interpreted by serology. Of the individuals tested, 11% were HLA-DR homozygous by RFLP. Our results demonstrate an important clinical potential of RFLP typing for the typing of bone marrow transplant candidates in whom serology often fails, and for kidney transplant candidates with "blanks" or serologically "difficult" HLA antigens.

UI	MeSH Term	Description	Entries
D012150	Polymorphism, Restriction Fragment Length	Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment.	RFLP,Restriction Fragment Length Polymorphism,RFLPs,Restriction Fragment Length Polymorphisms
D006650	Histocompatibility Testing	Identification of the major histocompatibility antigens of transplant DONORS and potential recipients, usually by serological tests. Donor and recipient pairs should be of identical ABO blood group, and in addition should be matched as closely as possible for HISTOCOMPATIBILITY ANTIGENS in order to minimize the likelihood of allograft rejection.

D006684	HLA-DR Antigens	A subclass of HLA-D antigens that consist of alpha and beta chains. The inheritance of HLA-DR antigens differs from that of the HLA-DQ ANTIGENS and HLA-DP ANTIGENS.	HLA-DR,Antigens, HLA-DR,HLA DR Antigens

D000483	Alleles	Variant forms of the same gene, occupying the same locus on homologous CHROMOSOMES, and governing the variants in production of the same gene product.	Allelomorphs,Allele,Allelomorph
D012703	Serotyping	Process of determining and distinguishing species of bacteria or viruses based on antigens they share.	Serotypings
D014181	Transplantation Immunology	A general term for the complex phenomena involved in allo- and xenograft rejection by a host and graft vs host reaction. Although the reactions involved in transplantation immunology are primarily thymus-dependent phenomena of cellular immunity, humoral factors also play a part in late rejection.
