Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 3 spans almost 200 million base pairs (the building material of DNA) and represents about 6.5 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 genome annotation their predictions of the number of genes on each chromosome varies. In January 2017, two estimates differed by 16%, with one estimate giving 2,971[2] genes, and the other estimate giving 2,565[3] genes.

Genes[edit]

The following are some of the genes located on chromosome 3:

  • AMOTL2: encoding protein]] Angiomotin-like protein 2
  • APEH: encoding enzyme Acylamino-acid-releasing enzyme
  • AZI2: encoding protein 5-azacytidine-induced protein 2
  • C3orf23: encoding protein Uncharacterized protein C3orf23
  • C3orf60/NDUFAF3: encoding enzyme NADH dehydrogenase [ubiquinone] 1 alpha subcomplex assembly factor 3
  • C3orf70: encoding protein C3orf70 (Chromosome 3 Open Reading Frame 70)
