The follow-up of 523 kidney transplants with grafts from full-house donors shows a significant (p less than 0.02) correlation between the graft survival and the HL-A match grade. There was no indication in this study that kidneys from blood-group O donors do better in group O recipients than in non-O recipients. Neither was it possible to show any effect of matching for either of the haplotypes, HL-A1,8, HL-A3,7, or HL-A2,12.
