Chromosome 13

Chromosome 13 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 13 spans about 113 million base pairs (the building material of DNA) and represents between 3.5 and 4% of the total DNA in cells.

The following are some of the gene count estimates of human chromosome 13. 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.

The following is a partial list of genes on human chromosome 13. For complete list, see the link in the infobox on the right.

The following diseases and disorders are some of those related to genes on chromosome 13:

The following conditions are caused by changes in the structure or number of copies of chromosome 13:
