Through studies of the distribution of HL-A antigens in a family and related donor selection on the basis of genotyping, excellent results have been achieved in cases of donor-recipient HL-A identity. Similar good results may be achieved in cases of donor-recipient monoallelic compatibility where the donor's nonshared allele is not associated with a major detectable HL-A antigen. In instances of monoallelic incompatibility where donor's nonshared allele is associated with a single detected HL-A antigen, the individual "strengths" of these antigens can be estimated on the basis of the clinical course of the recipient and studies of renal function and histology.
