Everyone has two copies of each chromosome, so you have two sixth chromosomes. Chromosome 6 is one of the 23 pairs of chromosomes in humans. It spans almost 171 million base pairs and comprises about 6% of the total DNA in our cells. It carries a lot of important genes, including those involved in the immune system, such as the Major Histocompatibility Complex (MHC). The MHC genes are crucial for recognizing and fighting off foreign invaders like viruses and bacteria.
Chromosome 6 is also linked to many other important functions, including:
- Immune system: The MHC genes on chromosome 6 play a vital role in immune system function.
- Development: Genes on chromosome 6 are involved in the development of many body systems.
- Metabolism: Some genes on chromosome 6 influence how our bodies process food and energy.
Certain genetic variations on chromosome 6 can also be associated with an increased risk of developing certain diseases, like:
- Autoimmune disorders: The MHC genes can contribute to the development of autoimmune diseases, where the immune system mistakenly attacks healthy cells.
- Cancer: Some genes on chromosome 6 are linked to cancer development.
- Neurological conditions: Chromosome 6 may influence the development of certain neurological conditions.
