Chromosome 12 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 12 spans about 133 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.

Chromosome 12 contains the Homeobox C gene cluster.

Genes

[edit | edit source]
See also: Category:Genes on human chromosome 12.

The following are some of the gene count estimates of human chromosome 12. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). Among various projects, the collaborative consensus coding sequence project (CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes.[5]

G-banding patterns of human chromosome 12 in three different resolutions (400,[12] 550[13] and 850[4]). Band length in this diagram is based on the ideograms from ISCN (2013).[14] This type of ideogram represents actual relative band length observed under a microscope at the different moments during the mitotic process.[15]
