Chromosome 17

Definition
noun
In humans, the autosome that spans about 83 million base pairs, likely to contain about 1200 genes, and with a submetacentric chromosome
Supplement
In humans, the chromosomes occur in pairs and a typical somatic cell would contain 23 pairs of chromosomes in the nucleus. Each of these pairs has a characteristic length and banding pattern. There are two types of chromosomes: autosomes and allosomes. There are also two sets: the first set comes from the mother and the second set, from the father. Using idiograms, each chromosome may be identified one from the other based on the relative size and the banding pattern.
Chromosome 17 is a submetacentric autosome. It spans almost 83 million base pairs (i.e. about 2.5 to 3 % of the total DNA). It is likely to contain about 1200 genes. Some of the genes found on this chromosome are ARHGAP44 (coding for Rho GTPase activating protein 44), GGT6(for gamma-glutamyltransferase 6), NBP (for neuropeptide B), NXPH3 (for neurexophilin-3), STH (for saitohin), TAC4 (for tachykinin-4), TTYH2 (for tweety family member 2), VPS25 (for vacuolar protein-sorting-associated protein 25), and ZNF207 (for zinc finger protein 207).
Some of the diseases and disorders related to the genes on chromosome 17 include Bruck syndrome, Canavan disease, cystinosis, depression, and galactosemia.
