Human Leukocytes Antigens Determine Susceptibility to Blastocystis hominis

The human major histocompatibility complex (HMC) is known as human leukocyte antigen (HLA). The gene products of this region are encoded by a cluster of genes located on the short arm of chromosome 6 that are involved in interactions with T-cells (Cunliffe and Trowsdale, 1987). HLA system is highly highly polymorphic and polymorphisim is the existence of two or more alleles of a gene at a single locus in a population, where the occurrence of the alleles is greater than can be explained by recurrent mutation alone. Gene polymorphism in the MHC region is the most extensive yet described ISSN: 2319-7706 Volume 4 Number 3 (2015) pp. 499-503 http://www.ijcmas.com
