Distribution of HLA antigens in two Arab populations in Iraq

ABSTRACT

Background: HLA is the mast highly polymorphic gene system in the human body and hence in the population, whether they are ethmic [Caucasoid, Orientals and Negros] or their religions [Muslims, Christians and Jewish]. This extensive polymorphism of HLA genes therefore make it very unlikely that two random individuals will express identical set of HLA molecules. Iraq is one of the countries that had many ethmic group like Arab Muslims and Arab Christians who lived many provinces. HLA study of these two groups was important for determining the heterogeneity in Iraqi people
