The complete sequence of chromosomes 1 through 22, plus X and Y, is 3.3 billion chemical letters, or bases, long. Although the actual number is not yet known, scientists have estimated that there are between 30,000 and 100,000 genes in the human genome. Knowing the complete human genome sequence helps researchers locate and identify disease genes. This knowledge will improve early detection and diagnosis of disease. It will also promote novel drug design and therapies that can be tailored to an individual to reduce potential side effects.
Gene therapy is the use of genes to treat disease.
This field holds great potential for treating and curing disease. Gene therapy uses functional genes to replace defective genes that cause disease. It can also be used to bolster the body's own immune system to fight both genetic and acquired disease. Our purpose is to provide the public with understandable information about the importance of genomics and the possible impact genetic information may have on their lives, thus enabling them to make informed decisions.
