Haptoglobin polymorphism in Hungary

The haptoglobin phenotype was determined in 2609 blood samples collected from every Hungarian county. The results of the nation-wide survey are in agreement with those of a series of previous studies in which only Budapest inhabitants were investigated. However, a statistically significant difference was found in the haptoglobin phenotype frequency and distribution of people living west and east of the Danube. A lower HP*1 frequency was observed in the inhabitants of the eastern part of Hungary when compared to those living in the western part.
