Chromosome 17

Chromosome 17

What is chromosome 17?

Chromosome 17 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 17 spans more than 81 million base pairs (the building material of DNA) and represents between 2.5 and 3 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 17 likely contains between 1,200 and 1,500 genes.

Genes on chromosome 17 are among the estimated 30,000 to 40,000 total genes in the human genome.

There are many conditions related to genes on chromosome 17.

Is there a standard way to diagram chromosome 17?

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.
