Chromosome 3 (human)



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.

Additional recommended knowledge

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 3 likely contains between 1,100 and 1,500 genes.

Genes

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

  • ALAS1: aminolevulinate, delta-, synthase 1
  • BTD: biotinidase
  • CCR5: chemokine (C-C motif) receptor 5
  • CPOX: coproporphyrinogen oxidase (coproporphyria, harderoporphyria)
  • HGD: homogentisate 1,2-dioxygenase (homogentisate oxidase)
  • MCCC1: methylcrotonoyl-Coenzyme A carboxylase 1 (alpha)
  • MITF: microphthalmia-associated transcription factor
  • MLH1: mutL homolog 1, colon cancer, nonpolyposis type 2 (E. coli)
  • PCCB: propionyl Coenzyme A carboxylase, beta polypeptide
  • PDCD10: programmed cell death 10
  • PIK3CA: phosphoinositide-3-kinase, catalytic, alpha polypeptide
  • RAB7: RAB7, member RAS oncogene family
  • SCN5A: sodium channel, voltage-gated, type V, alpha (long QT syndrome 3)
  • SLC25A20: solute carrier family 25 (carnitine/acylcarnitine translocase), member 20
  • TMIE: transmembrane inner ear
  • USH3A: Usher syndrome 3A
  • VHL: von Hippel-Lindau tumor suppressor
  • ZNF9: zinc finger protein 9 (a cellular retroviral nucleic acid binding protein)
