what does haploidentical mean
Haploidentical Transplants. An HLA-haploidentical donor shares a haplotype with the transplant recipient. This means that the donor and recipient have the same set of closely linked HLA genes on one of the two Number 6 chromosomes they inherited from their parents.Rather than being a perfect match for each other, they are a half-match.his option has its roots at the Hutch, the first place to have an unrelated donor programâa list of about 200 people, including Hutch employees, willing to donate to a stranger. That program eventually developed into the National Marrow Donor Program.
