Chromosome 10
Reviewed August 2007
What is chromosome 10?Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 10, one copy inherited from each parent, form one of the pairs. Chromosome 10 spans about 135 million DNA building blocks (base pairs) and represents between 4 percent and 4.5 percent of the total DNA in cells. Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 10 likely contains between 800 and 1,200 genes. These genes perform a variety of different roles in the body. Genes on chromosome 10 are among the estimated 20,000 to 25,000 total genes in the human genome. How are changes in chromosome 10 related to health conditions?Many genetic conditions are related to changes in particular genes on chromosome 10. This list of disorders associated with genes on chromosome 10 provides links to additional information. Changes in the structure or number of copies of a chromosome can also cause problems with health and development. The following chromosomal conditions are associated with such changes in chromosome 10.
Is there a standard way to diagram chromosome 10?Geneticists use diagrams called ideograms as a standard representation for chromosomes. Ideograms show a chromosome's relative size and its banding pattern. A banding pattern is the characteristic pattern of dark and light bands that appears when a chromosome is stained with a chemical solution and then viewed under a microscope. These bands are used to describe the location of genes on each chromosome. See How do geneticists indicate the location of a gene? in the Handbook.
