Recombinational and mutational hotspots within the human lipoprotein lipase gene.

ABSTRACT: Here an analysis is presented of the roles of recombination and mutation in shaping previously determined haplotype variation in 9.7 kb of genomic DNA sequence from the human lipoprotein lipase gene (LPL), scored in 71 individuals from three populations: 24 African Americans, 24 Finns, and 23 non-Hispanic whites. Recombination and gene-conversion events inferred from data on 88 haplotypes that were defined by 69 variable sites were tested. The analysis revealed 29 statistically significant recombination events and one gene-conversion event. The recombination events were concentrated in a 1.9-kb region, near the middle of the segment, that contains a microsatellite and a pair of tandem and complementary mononucleotide runs; both the microsatellite and the runs show length variation.
