Key facts
- Our genomes are 99.9% the same as the genomes of other individuals.
- It is the 0.1% difference that interests us in healthcare.
- The difference or variation in our genomes is what makes each of us unique.
- Most variation causes no harm, but some have serious consequences and can impact on health.
Did you know?
- As well as sharing around 99.9% of the genome with each other, we also share 96% with chimpanzees, 90% with mice and 60% with bananas.
- Although it seems small, the 0.1% variation in the 3 billion letters of our genome equates to around 3 million differences.
- Individuals may have the same genetic changes linked to a condition, but this does not mean they will present with similar or even any symptoms.
