Genetic studies of low abundance human plasma proteins. VIII. Inherited structural variation in antithrombin III.
Genetically determined structural polymorphism of antithrombin III has been observed using ultra narrow pH polyacrylamide isoelectric focusing gels, followed by immunoblotting. The products of three alleles at the antithrombin III structural locus have been detected in normal U.S. white and black blood donors. The frequencies of the three alleles, AT III* 1, AT III* 2 and AT III* 3, respectively, are: 0.878, 0.103, 0.019 in whites and 0.916, 0.068, 0.016 in blacks. Family data from a large number of families establish an autosomal codominant pattern of inheritance of the three alleles.
