Genetic Variation: We're More Different than We Thought

New research shows that at least 10 percent of genes in the human population can vary in the number of copies of DNA sequences they contain—a finding that alters current// thinking that the DNA of any two humans is 99.9 percent similar in content and identity.

This discovery of the extent of genetic variation, by Howard Hughes Medical Institute (HHMI) international research scholar Stephen W. Scherer, and colleagues, is expected to change the way researchers think about genetic diseases and human evolution.

Genes usually occur in two copies, one inherited from each parent. Scherer and colleagues found approximately 2,900 genes—more than 10 percent of the genes in the human genome—with variations in the number of copies of specific DNA segments. These differences in copy number can influence gene activity and ultimately an organism's function.

To get a better picture of exactly how important this type of variation is for human evolution and disease, Scherer's team compared DNA from 270 people with Asian, African, or European ancestry that had been compiled in the HapMap collection and previously used to map the single nucleotide changes in the human genome. Scherer's team mapped the number of duplicated or deleted genes, which they call copy number variations (CNVs). They reported their findings in the November 23, 2006, issue of the journal Nature.

Scherer, a geneticist at the Hospital for Sick Children and the University of Toronto, and colleagues searched for CNVs using microarray-based genome scanning techniques capable of finding changes at least 1,000 bases (nucleotides) long. A base, or nucleotide, is the fundamental building block of DNA. They found an average of 70 CNVs averaging 250,000 nucleotides in size in each DNA sample. In all, the group identified 1,447 different CNVs that collectively covered about 12 percent of the human genome and six to 19 percent of any given chromosome—far more widespread than p
