Trinucleotide repeat polymorphism within the human antithrombin gene (AT3): allele frequency data for three population groups

The fifth intron of the human antithrombin gene (AT3) of chromosome 1q23 contains a highly polymorphic short tandem repeat based on the trinucleotide repeat [ATT]. Alleles range in size from [ATT]5 to [ATT]18, and can be typed using the polymerase chain reaction. Here we report allele frequency population data for Caucasians, Blacks and Southeast Asians. Statistical analyses demonstrate consistency with Hardy-Weinberg equilibrium for all three …
