Abstract

Allelic variation in 9.7 kb of genomic DNA sequence from the human lipoprotein lipase gene (LPL) was scored in 71 healthy individuals (142 chromosomes) from three populations: African Americans (24) from Jackson, MS; Finns (24) from North Karelia, Finland; and non-Hispanic Whites (23) from Rochester, MN. The sequences had a total of 88 variable sites, with a nucleotide diversity (site-specific heterozygosity) of .002+/-.001 across this 9.7-kb region. The frequency spectrum of nucleotide variation exhibited a slight excess of heterozygosity, but, in general, the data fit expectations of the infinite-sites model of mutation and genetic drift. Allele-specific PCR helped resolve linkage phases, and a total of 88 distinct haplotypes were identified. For 1,410 (64%) of the 2,211 site pairs, all four possible gametes were present in these haplotypes, reflecting a rich history of past recombination. Despite the strong evidence for recombination, extensive linkage disequilibrium was observed. The number of haplotypes generally is much greater than the number expected under the infinite-sites model, but there was sufficient multisite linkage disequilibrium to reveal two major clades, which appear to be very old. Variation in this region of LPL may depart from the variation expected under a simple, neutral model, owing to complex historical patterns of population founding, drift, selection, and recombination. These data suggest that the design and interpretation of disease-association studies may not be as straightforward as often is assumed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
