Chromosome 8

Chromosome 8 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 8 spans about 146 million base pairs (the building material of DNA) and represents between 4.5 and 5.0% of the total DNA in cells.[5]

About 8% of its genes are involved in brain development and function, and about 16% are involved in cancer. A unique feature of 8p is a region of about 15 megabases that appears to have a high mutation rate. This region shows a significant divergence between human and chimpanzee, suggesting that its high mutation rates have contributed to the evolution of the human brain.[5]

Genes

Number of genes

The following are some of the gene count estimates of human chromosome 8. 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.[6]

Cytogenetic band
G-banding ideograms of human chromosome 8
G-banding ideogram of human chromosome 8 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 8 in three different resolutions (400,[16] 550[17] and 850[4]). Band length in this diagram is based on the ideograms from ISCN (2013).[18] This type of ideogram represents actual relative band length observed under a microscope at the different moments during the mitotic process.[19]
