You inherit half of your 6 antigens
from your mother and half from your father, so you will always match 3
antigens with each of your parents. You have a 25% chance of a total match
with a brother or sister, a 50-50 chance of matching 3 antigens, and a
25% chance that none of your antigens will match.
On average, even two unrelated people will have a 1-antigen
match; there’s a one in 10,000 chance that all 6 antigens will match.
But even if none of the antigens match, there is still a 90% success rate
for a living donor transplant, and an 80% success rate for an unmatched
cadaver kidney transplant. |
