Chromosome 6

Chromosome 6 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 6 spans nearly 171 million base pairs (the building material of DNA) and represents 5.5–6% of the total DNA in cells. It contains the major histocompatibility complex, which contains over 132 genes related to the immune response, and plays a vital role in organ transplantation.
