It now appears unequivocal that three markers exist in a linkage group in chromosome 6 of man: HLA-A,
HLA-B
and PGM3 (Fig. 1.) Tentatively, two other HLA loci and one Ir gene have been mapped close to
HLA-B
. The probable map order is HLA-A - HLA-C -
HLA-B
- HLA-D - Ir. The biological functions of these loci are unknown. However, HLA-A, B and C are important in allograft rejection. Other closely linked loci (
HDR
, CML) appear to be important in the first events of the allograft rejection (first set) and in generation of killer cells. HLA-D might be important in cellular recognition and graft-versus-host reactions (matching at HLA-D decreases the incidence and severity of graft-versus-host disease), and the Ir genes in the defense against infections.
HLA-B
and HLA-D loci are important markers in studies of disease susceptibility.
HLA-B
locus antigens HLA-B27 and HLA-B8 are frequently associated with arthritic or autoimmune disorders. HLA-D determinants have been found in association with multiple sclerosis and C2 deficiency (HLA-DW2); juvenile diabetes and Addison's disease (HLA-DW3) and adult type of rheumatoid arthritis (HLA-DW4).
