HLA compatibility can be predicted by matching only three residues with outward oriented sidechains.
A new method of residue matching based on three polymorphic upward-oriented amino acid residues on the alpha-helices of the HLA molecule is described. The projected 10-year graft outcome for 1232 transplants with none of these residues mismatched was 47%, essentially the same as for 0 BDR-mismatched kidneys. The projected impact of allocation to recipients in a local pool based on the three residues was a 5% improvement in overall graft survival at 10 years.
