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 83 million base pairs (the building material of DNA) and represents between 2.5 and 3% of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies. In January 2017, two estimates differed by 9%, with one estimate giving 2,432[2] genes, and the other estimate giving 2,653[3] genes.

Chromosome 17 contains the Homeobox B gene cluster.

Diseases and disorders

Inactivating PH mutation in either the EVER1 or EVER2 genes, which are located adjacent to one another on chromosome 17 causes Epidermodysplasia verruciformis.

G-banding ideograms of human chromosome 17
G-banding ideogram of human chromosome 17 in resolution 850 bphs. Band length in this diagram is proportional to base-pair length. This type of ideogram is generally used in genome browsers (e.g. Ensembl, UCSC Genome Browser).
G-banding patterns of human chromosome 17 in three different resolutions (400,[5] 550[6] and 850[7]). Band length in this diagram is based on the ideograms from ISCN (2013).[8] This type of ideogram represents actual relative band length observed under a microscope at the different moments during the mitotic process.[9]
