Human Leukocyte Antigen (HLA) Typing:
HLA is a gene complex that encodes the Major Histocompatibility Complex or MHC proteins in humans.
These are cell surface proteins that help regulate the immune system. Half of the HLA markers that you
poses are inherited from your mother and the other half from your father, so each sibling sharing the
same parents, will have a 25% chance of being a close HLA match.
An HLA match is the number of HLA markers two people have in common, hence the more markers they
share, the better is the match said to be. Having a “good match” between two people means that their
immune systems will not recognize each other as foreign and the likelihood of rejection by either
decreases drastically.
Identification of polymorphism of human leukocyte antigens or allele (HLA) is important in solid as wells
as hematopoietic stem cell transplants.
