Simple repetitive DNA sequences are a widespread and abundant feature of genomic DNA. The following several features characterize such sequences: (1) they typically consist of a variety of repeated motifs of 1 10 bases-but may include much larger repeats as well; (2) larger repeat units often include shorter ones within them; (3) long polypyrimidine and poly-CA tracts are often found; and (4) t...
Genetic variation and willingness to participate in epidemiologic research: data from three studies.
The differences in common genetic polymorphism frequencies by willingness to participate in epidemiologic studies are unexplored, but the same threats to internal validity operate as for studies with nongenetic information. We analyzed single nucleotide polymorphism genotypes, haplotypes, and short tandem repeats among control groups from three studies with different recruitment designs that in...
Systematic analysis of short tandem repeats in 38,095 exomes provides an additional diagnostic yield
BACKGROUND Ancestral reconstructions of mammalian genomes have revealed that evolutionary breakpoint regions are clustered in regions that are more prone to break and reorganize. What is still unclear to evolutionary biologists is whether these regions are physically unstable due solely to sequence composition and/or genome organization, or do they represent genomic areas where the selection ag...
Copy number polymorphisms of nucleotide tandem repeat (TR) regions, such as microsatellites and minisatellites, are mutationally reversible and highly abundant in eukaryotic genomes. Studies linking TR polymorphism to phenotypic variation have led some to suggest that TR variation modulates and majorly contributes to phenotypic variation; however, studies in which the authors assess the genome-...
