Short tandem-repeat polymorphism/alu haplotype variation at the PLAT locus: implications for modern human origins.

ABSTRACT: Two dinucleotide short tandem-repeat polymorphisms (STRPs) and a polymorphic Alu element spanning a 22-kb region of the PLAT locus on chromosome 8p12-q11.2 were typed in 1,287-1,420 individuals originating from 30 geographically diverse human populations, as well as in 29 great apes. These data were analyzed as haplotypes consisting of each of the dinucleotide repeats and the flanking Alu insertion/deletion polymorphism. The global pattern of STRP/Alu haplotype variation and linkage disequilibrium (LD) is informative for the reconstruction of human evolutionary history. Sub-Saharan African populations have high levels of haplotype diversity within and between populations, relative to non-Africans, and have highly divergent patterns of LD. Non-African populations have both a subset of the h
