title: Relationship between Hp1S and Hp2 gene frequencies among human populations.
abstract: In this work, we present new data on the Hp1alpha- and Hp2alpha-chains polymorphism in different populations. We confirm the singularity of the geographical distribution of the Hp2 alleles in our samples. The analysis of the results shows that a significant correlation exists in the population between the Hp1S and Hp2 gene frequencies. An additional Hp1alpha-chain variant is described in a Pyrenean sample.
