DNA :: Discover why some people are susceptible to certain diseases

Researchers have successfully sequenced the DNA of 15 mouse strains most commonly used in biomedical research. More than 8.3 million genetic variations, or single nucleotide polymorphisms (SNPs), were discovered among the genomes of the 15 mouse strains. These new data on laboratory mice will help researchers better understand what makes some individuals more susceptible than others to certain diseases, and will serve as a valuable resource as researchers determine the role that various environmental substances may play in the development of disease.

The ?Resequencing and SNP Discovery Project? led by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, and its National Toxicology Program, began less than two years ago with a $13 million budget.
