Chromosome 22 was the first human chromosome to have been sequenced.
My genome, your genome, their genome… and then what?
The human genome was sequenced in 2000. The news broke as though we had just unravelled the mystery of human life. Yet, we still know very little.
anti-arsenic
AS3MT: gene coding for a protein that modifies arsenic and makes it less toxic. Adaptation to arsenic serves as a model for how organisms evolve to survive under toxic conditions.

antiviral
APOBEC3G: Gene involved in antiviral defense.
Smurfs
CYB5R3: gene coding for a protein that is involved in the redox of iron atoms in hemoglobin. Variations in this gene are associated with hemoglobin that binds oxygen less efficiently. Carriers have bluish (cyanotic) skin.
