major histocompatibility complex

n. Abbr. MHC
A group of genes in humans and most other vertebrates that code for cell-surface glycoproteins (called MHC molecules) which function in the immune system and also are principally responsible for determining tissue compatibility in transplants.

The antigens of the HLA system are determined by genes present in the major histocompatibility complex which is located on the short arm at the 6th chromosome (6p21.3) in humans and extends over some 4 centimorgans of DNA, about 4 x[10.sup.6] base pair.
