title: Types and subtypes of haptoglobin in the Chinese population.
abstract: Haptoglobin phenotypes of 1121 unrelated Chinese blood donors in Beijing were determined. The gene frequency of Hp1 was 0.270. A rare variant, which we identified as Hp1S-J, was found. Two hundred and two samples of this population were submitted to haptoglobin subtyping, and no Hp1F allele was found among them.
