Genetic Variation Program
Genetic Variation Program Overview
Most of any one person's DNA, about 99.5 percent, is exactly the same as any unrelated person's DNA. Differences in the sequence of DNA among individuals are called genetic variation.
Genetic variation explains some of the differences among people, such as eye color and blood group. Genetic variation also plays a role in whether a person has a higher or lower risk for getting particular diseases. Single gene differences in individuals account for some traits and diseases, such as the ABO blood group, cystic fibrosis and sickle cell disease. More complex interrelationships among multiple genes and the environment are responsible for many common diseases, such as diabetes, cancer, stroke, Alzheimer's disease, Parkinson's disease, depression, alcoholism, heart disease, arthritis and asthma. The Genetic Variation program supports research on genetic variation and how it relates to diseases, responses to drugs and environmental factors.
The Genetic Variation Program supports research aimed at:
- Discovering and typing single nucleotide polymorphisms (SNPs) and other forms of genetic variation on a large scale across the genome.
- Developing high-resolution maps of genetic variation and haplotypes.
- Developing methods for the large-scale experimental and statistical analysis of SNPs, other forms of genetic variation, haplotypes and complex traits.
- Developing statistical methods to relate genetic variation to phenotype.
