α2-HS glycoprotein (AHSG/fetuin) is a human plasma protein that is polymorphic with two common alleles and many variants. To investigate molecular evolution at this locus, intragenic haplotypes was analyzed by a contiguous genomic sequencing, and their frequencies were determined for 309 subjects. Judging from the aligned nucleotide sequences in the human and chimpanzee genes, it was concluded that the type 1 allele is older and has evolved into four major suballeles. The type 2 allele was generated from one major branch of the type 1 allele. The AHSG gene had a low mutation rate and nonhomogeneous distribution of the substitutions.
